After the Supreme Court ruled that the prorogation was illegal, MPs returned to Westminster.
The PA news agency looks at key dates that could influence when, how, and if Britain leaves this year’s European Union.
September 25
After Speaker John Bercow declared that Parliament would resume on Wednesday, MPs took seats on the green benches of the Commons.
Parliament was suspended, but it resumed without any state opening because Lady Hale, the president of the court, said that it had never been prorogued.
September 29
Manchester will host the Conservative Party’s annual conference. However, it is not clear how many MPs will attend.
Parliament normally enters a conference recess in order to allow parliamentarians access to the party gatherings. However, with the Commons back in business, they might not be able.
The Government could submit a motion for a brief recess but will need to get the support of opposition MPs who are less likely to sympathize with the Conservatives now.

September 30
Antti Rinne, the Finnish prime minister, demanded that the PM outline his plans to EU leaders by September 30th.
However, the Government has stated that Boris Johnson will not be obliged to submit formal written proposals by an “artificial deadline”.
October 14
After the prorogation, the Queen was to officially open Parliament. Her speech would outline the Government’s new legislative agenda.
It could still occur on this date if Parliament is prorogued once more in the interim, or it may be brought back or pushed back.
It is unlikely that a state opening will occur before then, as the Queen is still at Balmoral and is not expected to return until the middle of next month.
Following the Supreme Court judgement (House of Commons/PA), MPs returned to Commons on Wednesday
October 16-17
The Prime Minister will travel to Brussels to attend what is believed to be the UK’s last European Council summit.
He stated that he hopes to negotiate a new or amended agreement with the EU at the Brussels gathering so he can deliver Brexit later this month.
However, Theresa May has not yet received formal proposals on how to alter the deal.
October 19
The so-called Benn Act is designed to prevent a no deal Brexit. The Government will have to request a delay beyond Oct 31 unless a divorce agreement is approved or Parliament agrees that the EU will leave the EU without one by Oct 19.
If there is no agreement, the PM will have to write to the president to request an extension to Article 50 to January 31.
October 31
Unless an extension is reached by the EU, the date at which Britain is due to leave the European Union is the date.
Johnson repeatedly stated that he will not accept any delay beyond this date. He said he would rather be “dead on a ditch” than allow Britain to remain in the EU.
– November or Dezember
The Government twice asked MPs for their support in a general election. Opposition parties voted against it because they fear a no-deal Brexit could occur during the campaign, when Parliament wouldn’t be sitting.
Instead, MPs have stated that they will support an electoral election once the Government has extended Britain’s EU membership. This could lead to an election in November or December.
