David Cameron is getting ready to unveil the rest of his new government - and risk angering senior Conservatives forced to make way for their Liberal Democrat coalition partners.
After announcing his Cabinet on Wednesday night, the Prime Minister is chairing its first meeting as he seeks to demonstrate he is getting down to business.
But he will also be filling out the middle-ranking and junior roles in the Tory-Lib Dem administration.
The new Cabinet features five Lib Dems, including Deputy Prime Minister Nick Clegg, Business Secretary Vince Cable, Energy Secretary Chris Huhne, Treasury Chief Secretary David Laws and Scotland Secretary Danny Alexander.
Former Tory leader Iain Duncan Smith has also been awarded the job of Work and Pensions Secretary in what was being seen as a sop to the right of the party amid concerns about the alliance with the Lib Dems.
The appointments meant some senior Tories were not given full Cabinet positions, including Chris Grayling, Dominic Grieve and Theresa Villiers.
Another 15 Lib Dems are expected to be appointed to the lower ranks of the Government, creating even more pressure for places.
