Brexit latest: May, Raab and Corbyn face Sunday interviews - BBC News
Theresa May, Jeremy Corbyn and Dominic Raab face TV grillings over their Brexit positions.
Catherine Haddon, of the Institute for Government think tank, said the 25 November EU summit would probably have to be postponed if May loses a vote of confidence.

She would still be prime minister until a new Tory leader was elected, unless she resigned and handed over to a caretaker PM.

“It would have implications for the negotiations because we don’t know what the position of the new prime minister would be,” Ms Haddon told BBC News.

Appointing a caretaker PM would be “quite problematic” because the party is divided and would be unlikely to agree on a suitable candidate.

The whole Tory leadership process takes about two months, although they could shorten it, but they would “have to say to the EU, and the public, we will come back in January and try to get through the leadership contest between now and then”.

That would take us even closer to the 29 March, the scheduled departure date, and make it even tighter to get the required Brexit legislation through Parliament in time.

Tory MPs will be conscious of the time pressure and if she survives this week then the chances of her being ousted are reduced, argued Ms Haddon.

She could face another “pressure point” when MPs vote on the deal, which might lead to another attempt to get her out.

If she won a vote of confidence it would “strengthen her hand quite considerably,” she adds.
