Would more competition in the sector, which is dominated by four big players, drive audit quality up? Do accountants need to be more robust in challenging company figures? Joining Evan Davis for The Bottom Line: Bill Michael, UK Chairman and Senior Partner at KPMG. Jac Berry, Audit Partner and UK Head of Quality at Mazars and Christopher Humphrey, Professor of Accounting at the Alliance Manchester Business School
