Downing Street and the government in general has been engulfed by allegations of cronyism in recent weeks. But there are many different strands to the story, some of which only tangentially overlap – here are the key threads you should be following.

Greensill lobbying

The story started with revelations that David Cameron had been lobbying the chancellor Rishi Sunak on the behalf of Greensill Capital. The prime minister had tried to get the bank access to a taxpayer-backed loan scheme, and Sunak told officials have another look. The bank has since collapsed, and the Treasury is now potentially on the hook for loans it underwrote for Greensill under a related scheme.
