Mrs May could head north of the border as early as tomorrow, the Daily Mail reported, in a bid to convince people that the deal she struck with the European Union is the best, and only deal possible.

Theresa May told Brexit deal is a '˜huge gamble'

The tour of the regions and nations of the United Kingdom comes as the Prime Minister faces mounting opposition to the draft withdrawal agreement she signed earlier this month.

Mrs May has stepped up her bid to win round enough public support for the deal, which critics say subjects the UK to EU rules without a say in how they are implemented, and weakens the integrity of the Union.

As many as 100 of Mrs May’s own MPs could reject the deal during a ‘meaningful vote’ in parliament, expected to take place on December 11.

The majority of Labour politicians, and all of the bloc of SNP politicians, are also set to vote against the deal, meaning its chances of passing remain perishingly small for the Prime Minister.
