The Prime Minister launches a charm offensive today to sway MPs to accepting her Brexit deal - but one has already told her he will not support it.

Folkestone and Hythe MP Damian Collins said he will not back the agreement this morning, citing concerns over the backstop arrangements which could keep the UK locked in a customs union.

He sparked controversy last week when he became the first Tory MP in Kent to call for a second referendum.

Yesterday, the EU's other 27 nations said it would support the draft withdrawal agreement published earlier this month.

Parliament will have the final say on whether the proposals are accepted in a vote of MPs on December 12.

Yet there are huge doubts on whether it will be approved, with Labour, the Liberal Democrats, the SNP, the DUP and many Conservatives saying they will vote against it.

Mr Collins tweeted: "I will not be voting for the EU withdrawal agreement, as agreed by the European Council, when it comes to the House of Commons on 12th December.

"The backstop arrangements would keep us locked in the customs union with no independent means to leave; other leaders will exploit this."

The Prime Minister warned MPs not to vote against the deal.

She said: "It will be one of the most significant votes that Parliament has held for many years.

"On it will depend whether we move forward together into a brighter future or open the door to yet more division and uncertainty."
