Theresa May has written to MPs outlining the options ahead for Brexit.
"The Council's decisions mean we have a clear choice," the prime minister wrote.
"1. We can revoke Article 50 - but that would be to betray the result of the referendum.
"2. We can leave with no deal on 12 April - but the House has previously said this is not something it will support.
"3. If it appears that there is not sufficient support to bring the deal back next week, or the House rejects it again, we can ask for another extension before 12 April - but that will involve holding European Parliament elections.
"4. If it appears that there is sufficient support and the Speaker permits it, we can bring the deal back next week and if it is approved we can leave on 22 May."
