The Conservatives and Liberal Democrats have already discussed forming a second coalition after the next general election, a new book has claimed.
Matthew d'Ancona also claims in In It Together that Nick Clegg, the deputy prime minister, has said that he could not form a coalition with, Ed Miliband, the leader of the Labour party.
D'Ancona writes: "From time to time, he [Mr Cameron] would raise the question of a second coalition with Clegg. 'If we did it again,' he mused to the deputy prime minister, 'I'd have to seek collective permission.' "
Meanwhile Jacob Rees-Mogg, Conservative MP for North East Somerset said that his party should make an electoral pact with the UK Independence party.
Rees-Mogg suggested that Nigel Farage's party would expect to get some MPs out of any deal, which he suggested was likely to be discussed next year.
The backbencher floated the idea of Conservatives making a "big, open and comprehensive" offer of coalition with Ukip to keep Labour out of power earlier this year.
"I'm not going to say which of my friends I think should make way for Ukip," he told Channel 4 News.
"Potentially some, some … Ukip would expect to get some members of parliament out of this, yes, yes, of course."
He added: "My view is that it is likely that there will be some discussions about how to do a deal in a year from now."
