Theresa May has slapped down one of her most senior Cabinet ministers after he said it is "very improbable" that the UK will remain a member of the single market if the country is to regain control of its borders.

The Prime Minister's spokesman said it is not right to be "putting all your cards on the table" and claimed David Davis was setting out "his opinion", not government policy, when he spoke in Parliament yesterday.

Mr Davis told the House of Commons that it is "a simple truth" that if the UK was forced to accept free movement of people it would be unlikely that the country could remain in the single market.
