 At Prime Minister's Questions on 17 January 2018, Labour leader Jeremy Corbyn challenged Prime Minister Theresa May over Carillion, asking why over £2bn of contracts had been awarded to Carillion even after the company had issued three profit warnings.Transport Secretary Chris Grayling faced calls to resign, having awarded a major HS2 rail contract to Carillion in July 2017.Particular concerns were raised about the National Health Service where 14 hospital trusts had relied on Carillion services and where construction of two major hospital PFI projects – the new Royal Liverpool University Hospital and the Midland Metropolitan Hospital in Birmingham – faced shutdowns and further delays; in March 2018 it was reported that costs on these two projects were over £70m higher than the company was officially reporting.
