HOW TONIGHT’S KEY VOTES WILL WORK...
■ MPs have seized control of the parliamentary timetable so they can hold a series of votes this evening to work out what kind of Brexit has a chance of winning the support of the Commons.
■ At 2pm, normal proceedings in the House will stop and MPs will debate for an hour whether to go ahead with Tory former minister Sir Oliver Letwin’s plan to stage indicative votes.
■ If they do, Commons Speaker John Bercow will at 3pm announce which Brexit options will go on the ballot paper. MPs had until last night to submit their suggestions.
■ At 5pm, while the debate is taking place, Theresa May is expected to address a meeting of the 1 22 Committee, the group made up of all backbench Conservative MPs.
■ At 7pm, MPs will be given paper slips listing the various Brexit options. They will get half an hour to mark Aye or No next to each one.
■ While the votes are being counted, MPs will debate legislation changing the Brexit date from March 2 to April 12, after Mrs May agreed an extension with EU leaders at a Brussels summit last week.
■ The Speaker will announce the results of the indicative votes at around pm in the Commons chamber, revealing whether any of them commanded majority support.
■ Mrs May has said she will not necessarily be bound by the result – particularly if it is ‘undeliverable’ because the EU would not agree to it.
■ However, MPs are planning to seize control of the parliamentary timetable again next Monday so they can repeat the process to refine the options or attempt to pass legislation to enforce them.
