The Prime Minister has warned that if her Brexit deal is rejected next week the UK "may never leave the EU."

In a speech in Grimsby on Friday lunchtime, Theresa May said that "no one knows what may happen" if the negotiated withdrawal agreement is voted down by MPs for a second time.

MPs are set to hold a second 'meaningful vote' on Mrs May's deal with the European Union on Tuesday.

The UK is set to leave the EU on March 29, but as yet Parliament has yet to ratify a deal.

The withdrawal agreement was rejected by MPs in January when 432 voted against and just 202 for the original terms.

Mrs May has since tried to renegotiate key passages of the agreement - most notably around the Backstop arrangements in Northern Ireland.

Further negotiations will take place ahead of Tuesday's vote, but the Prime Minister warned that it's fast approaching crunch time.

She said: "Next week MPs in Westminster face a crucial choice: whether to back the Brexit deal or to reject it.

"Back it and the UK will leave the European Union. Reject it and no one knows what will happen.

"We may not leave the EU for many months, we may leave without the protections that the deal provides. We may never leave at all."

Mrs May added: "Brexit does not belong to MPs in Parliament. It belongs to the whole country.

"It belongs to the people who voted for it and want to see it implemented so we can all move on to a prosperous future.

"And that more prosperous future also belongs to those who voted against Brexit and who expect politicians to make reasonable compromises to bring our country back together.

"Everyone now wants to get it done, move beyond the arguments, past the bitterness of the debate and out of the EU as a united country ready to make a success of the future."
