Former Prime Minister David Cameron has said he feels “desperately sorry” for those affected by the collapse of supply chain finance firm Greensill Capital, where his role as adviser and his lobbying of government officials has been heavily scrutinised.

“Since the collapse of Greensill Capital, many questions have been raised about my dealings with Lex Greensill in government, and my subsequent involvement with the company,” Cameron said in a statement released on 11 April.
