A thread about the 1010-day period from 23 June 2016 to 29 March 2019:

Day 1 of 1010: Referendum takes place. 52% vote to leave the EU.

Day 21 of 1010: Theresa May takes over from David Cameron as Prime Minister.

Day 37 of 1010: The government begins its legal fight to avoid needing parliamentary approval for the triggering of Article 50.

Day 216 of 1010: The government loses its legal fight to avoid needing parliamentary approval for the triggering of Article 50.

Day 225 of 1010: The government publishes a White Paper setting out its negotiating aims.

Day 264 of 1010: Parliament overwhelmingly approves the triggering of Article 50.

Day 280 of 1010: May triggers Article 50, setting the date of Brexit as day 1010.

Day 300 of 1010: May calls a general election, expecting to gain a bigger majority.

Day 350 of 1010: The general election wipes out May’s majority.

Day 362 of 1010: Formal negotiations between the EU and the UK government begin.

Day 534 of 1010: The EU and the UK agree that the Withdrawal Agreement must contain a framework to guarantee an open Irish border. Conservative reaction is broadly, if cautiously, positive.

Day 616 of 1010: The draft Withdrawal Agreement is published, with an early version of the so-called 'backstop' framework to keep the Irish border open. Conservative reaction is mixed.

Day 744 of 1010: At Chequers, the Cabinet briefly seems to agree a new negotiating position on the future UK-EU relationship, which would avoid the backstop. Conservative reaction is largely hostile, and government resignations quickly follow.

Day 821 of 1010: After a period of making increasingly sceptical noises, the EU formally rules out accepting the Chequers proposal.

Day 875 of 1010: The final Withdrawal Agreement is published, including a revised version of the backstop as requested by the UK. Conservative reaction is furious, and more government resignations follow.

Day 887 of 1010: May schedules a Commons vote on the Withdrawal Agreement for day 902.

Day 901 of 1010: May postpones the Commons vote on the Withdrawal Agreement until day 937.

Day 903 of 1010: Conservative MPs try and fail to topple May.

Day 937 of 1010: The Commons overwhelmingly rejects the Withdrawal Agreement.

Day 938 of 1010: Opposition MPs try and fail to topple the government.

Day 951 of 1010: After MPs call for “alternative arrangements” to the backstop, May announces that another vote will take place on day 967, following further talks with the EU.

Day 965 of 1010: May tells MPs that actually she wants to postpone until day 980, and then she’ll have something for them to vote on.

Day 967 of 1010: MPs do some voting anyway. They vote against requiring May to do what she said she would do by day 980, and they vote against nonbindingly noting what May said she would do by day 980. May responds by saying that she will do what she said she would do by day 980.

Days 971–3 of 1010: Eleven MPs resign from the Labour and Conservative parties to set up a new grouping, complaining about their former leaders’ handling of Brexit.

Day 977 of 1010: May says that in fact she won’t have an amended deal ready for day 980, but she will absolutely, definitely present something to MPs for a vote by day 993.

Day 993 of 1010: May returns with the same Withdrawal Agreement she negotiated 118 days ago, plus some only-just-published legal notes confirming that nobody wants the backstop to be permanent but the UK won’t have the right to leave it unilaterally. MPs throw the deal out again.

Day 994 of 1010: May tables a non-binding motion opposing no-deal, which MPs amend to non-bindingly oppose no-deal more loudly (but without specifying how to stop no-deal from happening automatically in 16 days), so May tries to defeat the motion. It passes, with no legal effect.

Day 995 of 1010: MPs vote for May’s proposal to request a delay to Brexit – either for three months to make preparations, if MPs change their minds and back May’s deal by day 1001, or, if they don’t, for an unspecified longer period, for an unspecified purpose.

Day 999 of 1010: The Speaker of the House of Commons announces that parliamentary conventions mean he cannot allow May to have another vote on her deal unless the proposal she puts forward has “substantial changes”.

Day 1001 of 1010: Disregarding the motion that she got MPs to pass six days ago, May asks EU leaders for a three-month extension so she can get her twice-rejected deal approved and implemented. The initial response suggests she would need to get the deal approved by MPs first.

Day 1002 of… 1024: EU leaders give May an unconditional two-week extension (until 12 April), which would increase to just under eight weeks (until 22 May) if MPs approve May’s deal “next week” (by day 1010).

Day 1008 of 1024: May tells Conservative MPs that if her deal passes, she’ll resign soon after. MPs hold “indicative votes” on eight other options, rejecting all of them.

Day 1010 of 1024: May brings the Withdrawal Agreement back to the Commons and MPs reject it for a third time, although not by such a huge margin as before. The EU's conditional offer of a few more weeks' extension expires.
