of corporate culture such as inclusion and diversity. The January 2018 collapse of the UK construction and services company Carillion raised further questions about the Big Four, all of which had advised the company before its liquidation. On 13 February 2018, the Big Four were described by Member of Parliament (MP) and chair of the Work and Pensions Select Committee Frank Field as "feasting on what was soon to become a carcass" after collecting fees of £72m for Carillion work during the years leading up to its collapse. The final report of a Parliamentary inquiry into the collapse of Carillion, published on 16 May 2018, accused the Big Four accounting firms of being a "cosy club", with KPMG singled out for its "complicity" in signing off on Carillion's "increasingly fantastical figures" and internal auditor Deloitte accused of failing to identify, or ignoring, "terminal failings". The report recommended the Government refer the statutory audit market to the Competition and Markets Authority (CMA), urging consideration of breaking up the Big Four. In September 2018, Business Secretary Greg Clark announced he had asked the CMA to conduct an inquiry into competition in the audit sector, and on 9 October 2018, the CMA announced it had launched a detailed study. In July 2020, the UK Financial Reporting Council told the Big Four that they must submit plans by October 2020 to separate their audit and consultancy operations by 2024.
