Big Boss Interview

Charles Stewart, chief executive of Sotheby's, joins the Big Boss Interview and discusses the scrutiny facing the art market over money laundering, the growth of digital art and NFTs, the expansion of sports collectibles, and how the conflict in the Middle East could affect the industry.
Stewart, who previously served as chief executive of a small bank before joining Sotheby’s, describes the characterisation of the industry as working with illicit money as a “misjudged notion”. He argues the company’s client base consists largely of established collectors, museum trustees and philanthropists who buy works to live with them rather than to obscure wealth.
Russian buyers — often cited in discussions about opaque art transactions — represented less than 1% of Sotheby’s global business when sanctions were imposed following the invasion of Ukraine, he says, challenging assumptions about the role of Russian money in the market.
Geopolitics is also shaping the art market. The Middle East has become an increasingly important region for Sotheby’s, with auctions in Riyadh and Abu Dhabi reflecting years of market development across the Gulf. Stewart says the company’s immediate priority amid escalating regional tensions is the safety of staff working there, though he notes market reaction to the latest conflict has so far been “somewhat muted”.
Stewart notes that countries including the United Arab Emirates, Qatar and Saudi Arabia are investing heavily in cultural infrastructure as part of longer-term economic diversification strategies. Institutions such as the Louvre Abu Dhabi — open for nearly a decade — and the forthcoming Guggenheim Abu Dhabi form part of plans to establish new global cultural destinations.
Despite these shifts, London remains central to Sotheby’s global operations. The company’s New Bond Street headquarters reflects more than 280 years of British heritage and the city continues to function as Sotheby’s second-largest sales centre after New York. A recent London auction achieved a 100% sell-through rate with bidders from 40 countries, demonstrating sustained international participation despite post-Brexit complications around import and export logistics.
The conversation also examines how technology is changing the art market. Stewart argues digital art represents a natural evolution in artistic practice rather than simply a speculative phenomenon linked to the boom and collapse of NFTs. He distinguishes between cryptocurrency speculation, the blockchain technology underlying NFTs, and the broader creative shift as artists adopt digital tools.
Sports memorabilia has also become a growing category for Sotheby’s. The market now extends beyond historic trophies and medals to include game-worn shirts and collectibles authenticated through technology that can match items to specific moments in matches. Stewart attributes the expansion partly to generational wealth transfer and to younger collectors’ interest in pre-owned objects with personal and cultural significance.

Anthony Houghton, Chief Executive of Holland & Barrett, joins the Big Boss Interview as social media and online self-diagnosis reshape how consumers approach health and wellness.
He describes a retail landscape where customers increasingly arrive in store — or online — having already decided what they need based on influencer content or digital health advice, not all of which is accurate or appropriate to their individual circumstances. In a £110 billion global health and wellness industry, the challenge for established retailers is navigating the gap between what customers believe products do and what they are legally permitted to claim.
Holland & Barrett’s response has been a major internal reset. Three years ago, the company invested in a dedicated science team to review its entire range. Of approximately 4,500 core products, 2,700 have since been reformulated or upgraded. More than 1,000 own-brand products have been completely overhauled in the past 18 months alone.
Labelling presents particular complexity. Products marketed for perimenopause, for example, may feature the term prominently on packaging to help customers find relevant items. Yet detailed ingredient information states that vitamin B6 contributes to hormonal regulation and iron supports normal cognitive function — without referencing perimenopause directly. Strict Advertising Standards Authority rules limit what retailers can claim about specific conditions, creating a disconnect between searchable labels and regulated ingredient statements. Houghton acknowledges many customers may not understand this distinction.
The transformation has coincided with strong financial performance. Holland & Barrett reported 11% sales growth — its third consecutive year of double-digit increases — with digital sales up 20% overall and accounting for 21% of total revenue. However, £300 million invested over three years in store refits, supply chain upgrades and internal capability building has weighed on profit margins. Houghton describes the investment as “fixing the foundations”, with efficiency gains expected to restore profitability as the transformation programme matures.
Despite digital growth, physical retail remains central to the strategy. The company operates 809 stores across the UK and Ireland, opened nine new sites this year and has completed a major refit programme. Houghton rejects suggestions that the High Street is dead, arguing that physical and digital channels are complementary rather than competitive. Stores now offer personal consultations, experiential elements such as yoga studios in selected locations, and partnerships with diagnostic provider Randox to deliver health MOT blood testing in a growing number of sites.
Cost pressures remain acute. Minimum wage increases affect the majority of staff across hundreds of stores. Holland & Barrett pays above the statutory National Living Wage and plans to announce another rise shortly. Rather than passing those costs directly to customers through price increases, the strategy focuses on driving operational efficiencies elsewhere. At the same time, the company has increased investment in colleague training — requiring staff to complete health and wellness training before advising customers — even as many retailers are cutting back.

Nicole Melillo Shaw, Managing Director of Volvo UK, joins Big Boss Interview at a pivotal moment for the electric vehicle market, as the company recalls 10,500 EX30 electric cars following four battery fires globally.
“It’s against everything we stand for,” she says, reflecting on a situation that challenges a brand built on nearly a century of safety leadership. Despite a global failure rate of just 0.02% and no fatalities, Volvo identified the root cause in late December and immediately instructed owners not to charge beyond 70% while a fix is implemented. Repairs are scheduled to begin in late March. For Volvo, the response reflects what she describes as a precautionary, safety-first culture, even when the commercial implications are uncomfortable.
Melillo Shaw examines what the recall means for consumer confidence in electric vehicles — a technology already under heightened scrutiny — even though petrol vehicles statistically present a greater inherent fire risk due to flammable fuel systems.
The recall comes as electric vehicle adoption remains slower than manufacturers once anticipated, despite annual growth exceeding 20%. Volvo’s UK electric sales peaked at 28% following the EX30 launch but have since stabilised at just over 22 per cent as more than 160 additional models enter the market and buyers opt for “one more petrol” or hybrid before fully switching.
Range anxiety, she argues, is no longer the central issue, but infrastructure concerns persist. Confusing government messaging — pairing incentives with discussions of pay-per-mile charges and benefit-in-kind changes — continues to add to consumer hesitation.
Global instability adds further complexity. Volvo has been regionalising production, partly in response to tariff pressures, building vehicles closer to the markets in which they are sold. That turbulence elevates the UK’s importance as Volvo’s third-largest market, where a direct-to-consumer model has delivered 40% growth and lifted market share from 2.5% to 3.5%.
Government Zero Emission Vehicle mandates now require manufacturers to meet steep electrification quotas or face fines of £12,000 per non-compliant vehicle from November. Volvo discontinued diesel models in the UK in 2023 and says it could sell 100% electric vehicles tomorrow if demand existed. However, meeting regulatory targets while absorbing development costs and discounting pressures presents a commercial balancing act.
Finally, Melillo Shaw reflects on her own trajectory — from Scunthorpe through healthcare brands to automotive leadership. Volvo deliberately recruited her because she had never bought a car, valuing the perspective of someone who understood the anxiety of a major purchase. She argues the industry must broaden access and challenge assumptions about who belongs in automotive careers, creating clearer pathways for talent from working-class communities.

Mark Allan, CEO of FTSE 100 property giant Landsec, tells Will Bain that much of the narrative around the UK’s commercial property market isn’t quite right. Demand for office space is robust: businesses are signing 15 to 20 year leases, and firms that downsized after COVID are reversing course. Even the fear that artificial intelligence will trigger mass job losses isn’t materialising just yet in leasing behaviour.
He is bullish on the future of retail. Allan believes the shopping centre is firmly “back”, with sales and rents climbing again at major destinations such as Liverpool ONE and Bluewater. Retailers, he says, have become more selective - closing weaker sites while doubling down on the biggest and strongest locations. And with no new centres being built, the most successful ones are only becoming more valuable.
But Allan is blunt about the challenges facing large scale development in the UK. The affordable housing market won’t improve until private development becomes financially viable again. Rising construction costs, slow and unpredictable planning processes and persistently high interest rates are making major projects far harder to get off the ground.
His sharpest criticism, though, is for Westminster. Allan argues that political instability is damaging investor confidence and making long term planning extremely difficult. Allan says the business rates system is "crazily out of date". He welcomes the government’s ambition for planning reform, but says the UK keeps being dragged back into cycles of “permanent drama” that undermine efforts to fix the system.

Clive Chesser, chief executive of PureGym, says surviving cancer fundamentally changed him as a leader — deepening his empathy and reshaping how he approached life, including changing career..
His diagnosis came during an extraordinarily difficult period in December 2021. While leading his then pub business through a complex private equity transaction, he was experiencing persistent breathlessness and fatigue he initially attributed to long COVID. After noticing swollen lymph nodes in his neck, members of his family — several of whom are senior doctors — urged him to undergo further tests. He completed them just before finalising the business deal.
Christmas brought what he describes as an unimaginable sequence of events. On Christmas Day, his father-in-law died while his wife isolated at home with COVID. Shortly afterwards, Chesser received confirmation that he had cancer in his lymph nodes. The following day, he says, he faced the hardest moment of his life: telling his three teenage children he had cancer.
At the time, Chesser was marathon-fit, training regularly and running annually. That physical condition proved critical during treatment. His fitness enabled him to tolerate more aggressive radiotherapy and additional chemotherapy rounds, improving his chances of full recovery — which he ultimately achieved. The experience, he says, transformed his sense of purpose and made his subsequent appointment as PureGym’s chief executive feel profoundly aligned with his personal journey.
That personal conviction underpins what he describes as a broader fitness revolution reshaping the UK gym industry. Nearly half — 47% — of PureGym’s January 2025 joiners were aged 25 or under, reflecting what Chesser sees as a generational shift in attitudes to health. Younger members, particularly Gen Z and Gen Alpha, are integrating fitness into their social identity. Gyms are becoming social hubs, not simply places to exercise, where mental wellbeing and community sit alongside physical strength.
He describes a trend he calls “fitness snacking” — members moving fluidly between gyms, boutique studios and fitness events before returning to a core membership. Despite this apparent transience, average tenure stands at 19 months and is rising. Most new joiners are returning members, a notable fact given PureGym’s no-contract, month-to-month model, where members actively choose to stay.
Women are driving another significant shift in the market, moving away from cardio-dominated routines towards strength and conditioning. In response, PureGym has introduced more than 50 women-only workout spaces across the UK after research showed many women prefer environments where they feel more comfortable and less exposed. These areas exist nationwide and sit alongside screened lighter-weight zones designed to reduce intimidation for first-time users. While the majority of PureGym’s 456 UK sites remain mixed-gender spaces, Chesser argues that offering choice has been critical to growth and inclusion.
Chesser also delivers a critique of the Labour government’s economic performance, arguing it has failed to deliver the long-term growth strategy promised before taking office. He points to National Insurance rises and the continued burden of business rates on bricks-and-mortar operators — including gyms and pubs — while online businesses face comparatively lighter structural costs.
He draws a stark comparison between government and business leadership, noting that the UK has had six Prime Ministers in ten years — instability he likens to running a football club rather than a company built on rolling five-year strategies and careful succession planning. In his view, the government remains trapped in short-term crisis management rather than long-term economic planning.
