PRIME MINISTER Theresa May has promised to give MPs a vote on extending Brexit negotiations or withdrawing from the EU without a deal if her plan is rejected next month.

In a dramatic statement to the House of Commons, Mrs May confirmed that she will put her Withdrawal Agreement – including whatever additional assurances she has secured from Brussels – to a "meaningful vote" by March 12.

If that fails, MPs will be offered two separate votes on the following days – one on a no-deal Brexit and, if that is defeated, the other on requesting an extension to the two-year Article 50 negotiation process to delay EU withdrawal beyond March 29.

The sequence of votes will be proposed in an amendable motion tabled by the Prime Minister for debate and vote in the Commons on Wednesday.

To uproar in the Commons, Mrs May told MPs: "They are commitments I am making as Prime Minister and I will stick by them, as I have previous commitments to make statements and table amendable motions by specific dates."

But she added: "Let me be clear, I do not want to see Article 50 extended. Our absolute focus should be on working to get a deal and leaving on March 29."

In a statement to MPs following a Cabinet meeting with senior colleagues at 10 Downing Street, Theresa May said she wanted to set out "three further commitments" to the Commons.

She said: "First, we will hold a second meaningful vote by Tuesday March 12 at the latest.

"Second, if the Government has not won a meaningful vote by Tuesday March 12, then it will - in addition to its obligations to table a neutral amendable motion under Section 13 of the EU Withdrawal Act - table a motion to be voted on by Wednesday March 13 at the latest, asking this House if it supports leaving the EU without a Withdrawal Agreement and a framework for a future relationship on March 29.

"So the United Kingdom will only leave without a deal on March 29 if there is explicit consent in the House for that outcome.

"Third, if the House, having rejected the deal negotiated with the EU, then rejects leaving on March 29 without a Withdrawal Agreement and future framework, the Government will on March 14 bring forward a motion on whether Parliament wants to seek a short, limited extension to Article 50."

If MPs vote for an extension, the Government will "seek to agree that extension approved by the House with the EU, and bring forward the necessary legislation to change the exit date commensurate with that extension", said Mrs May.
