The toppling of Mursell came as the Financial Reporting Council, which is examining Big Four accountant KPMG over its audit of Carillion, gave an update on its investigation today. The FRC has already carried out detailed interviews with audit team members and Carillion senior executives, and plans further interviews early this year. As well as KPMG, former finance directors Richard Adam and Zafar Khan are under investigation and the FRC widened the inquiry to cover KPMG’s 2016 audit today.
