Corbyn has called on other parties to back him in leading a caretaker govt.
"The political obstacles to Corbyn’s proposal are considerable"
Many MPs who might support the idea in theory would not want to install him in No.10 even as a caretaker PM.
Forming a caretaker government is more complicated than just choosing a PM
If opposition parties can agree on a PM, what would need to be agreed before a caretaker government could operate?
A government with ministers
MPs have a democratic obligation to bring Johnson down.
Corbyn must have the first attempt at replacing Johnson.
If that fails then there has to be x-party support for a unified figure.
A no confidence vote is not required.
Labour’s fear of losing the government cash awarded to opposition parties is hindering the formation of a caretaker government to oust Boris
Former Tory 'rebel' said.
Labour receives £7.9m in "Short money", awarded to opposition parties.
Jo Swinson isn't keeping Corbyn from leading a national unity government.
Former Labour and ex-Tory MPs have similar concerns.
For example, John Woodcock, Ian Austin and Gavin Shuker, will not vote to put a man they regard as unfit to be PM in No 10.
Corbyn supporters appear incapable to distinguish between:
Government of National Unity.
A minority government is formed of one party
A GNU is formed of all parties.
Corbyn wants a minority government
Everyone else wants a GNU
Row about signalling:
Swinson wants to reassure anti-Corbyn voters that the LibDems won’t result in a Corbyn PM.
Corbyn wants to paint Swinson as a closet Tory
The people whose preferences will decide if a government of national unity is formed are the independents.
Jeremy Corbyn "would support John Bercow as unity PM"
Corbyn has concluded that he wouldn't win the support needed to lead a government of national unity.
However, he might support another candidate as long as it is not a Labour or Conservative MP.
