Carillion
On 3 January 2018 Carillion, a company chaired by Green, announced that the Financial Conduct Authority was investigating the timeliness and content of the company's announcements from December 2016 regarding its financial situation. On 15 January 2018 Carillion was put into compulsory liquidation amidst widespread condemnation of its debt position and approach to risk in large contracts. Green said his responsibility was "full and complete, total – no question in my mind about that. Not necessarily culpability but full responsibility". Green was one of a number of former Carillion Directors described as "delusional characters" by House of CommonsSelect Committee Chairs Frank Field and Rachel Reeves. After further documentation and correspondence was published by the select committees, Carillion directors bosses were described by MPs as "fantasists" chasing "a pot of gold", with chairman Philip Green described by Rachel Reeves as having "either a woeful lack of leadership or no grip on reality," having advocated an "upbeat" messaging strategy five days before a profits warning. In the final report of the Parliamentary inquiry into the collapse of Carillion, published on 16 May 2018, Green was described as "delusional." The report concluded: The report also recommended that the Insolvency Service should consider whether the former Carillion directors, including Green, could be disqualified from acting as a director. The parliamentary process and findings have been questioned as lacking in objectivity and thoroughness, treating a highly complex situation in an incomplete manner. Former Carillion CEO Richard Howson, contends that Carillion was a victim of its public sector clients and that "any analysis as to the causes of the failure of Carillion is not complete without looking at the way in which government and the wider public sector procured services from Carillion and failed to administer payments."
