14.30 BST: MPs return from their summer recess. New Foreign Secretary Dominic Raab will be the first cabinet minister of the term to face questions from MPs.
15.30: Boris Johnson is expected to make a statement about the recent G7 summit in Biarritz. This could last for two hours or so.
17.30: There could be another ministerial statement, potentially on reported delays to the opening of the HS2 rail line.
After 17.00: If there is no further statement, an MP is expected to make a three-minute application to the Speaker John Bercow for an emergency debate on Brexit.
MPs will then be asked for their consent. If some MPs shout "no", 40 MPs in favour of the debate will need to stand up to ensure the debate goes ahead.
18.00-21.00: If approved, the emergency debate can last up to three hours.
21.00-22.00: MPs will vote on whether to take control of Parliament on Tuesday to extend the Brexit deadline to, at least, the end of January 2020. The vote could be as late as 22.00 BST.
Interesting times ahead
