Boris Johnson has ordered an independent review into Greensill Capital as a result of the David Cameron lobbying controversy. Nigel Boardman of Slaughter and May will lead the investigation into the now-collapsed finance firm’s activities in government and the role of its founder, Lex Greensill. The Whitehall review will look at how government contracts were secured by Greensill Capital and the role of the former PM in securing them.

So Dave won’t be sweating too much…
