During yesterday Prime Minister’s Questions, Sir William Cash asked Theresa May:

Sir William Cash (Stone) (Con): Will my right hon. Friend rule out introducing the withdrawal and implementation Bill if her withdrawal agreement is voted down yet again by the House next week, and then let the United Kingdom leave the European Union on 29 March, as per the people’s vote in 2016, as Parliament has enacted, and as the law requires?

The Prime Minister: What I have done today in writing to President Tusk is ask for that extension to article 50 until the end of June. I have been clear that, as I have said, I do not believe that Brexit should be delayed beyond that point. That would give us the opportunity to ensure that the House can consider again a deal, and then take forward the withdrawal agreement and implementation Bill in the circumstances that a deal was passed. In the circumstances that a deal was not passed, then it would obviously be necessary, as I have just said to my right hon. Friend the Member for West Dorset (Sir Oliver Letwin), for the House to consider how we should proceed. I would also say to my hon. Friend that, as he will have heard the Secretary of State for Environment, Food and Rural Affairs saying in the debate on no deal last week, there are particular issues, particularly in relation to the governance of Northern Ireland, in relation to leaving the European Union without a deal on 29 March. I continue to hope and continue to believe that the best way for this country to leave the European Union is to do so on the basis of a negotiated deal, and the extension to 30 June would allow us to do that.
