Theresa May was looking for three months, but she got only three weeks to try to push through her Brexit deal.
After Thursday’slate-night agreement among EU leaders to delay Brexit, the Prime Minister has until April 12 to get her twice-rejected deal over the line with MPs.
So, now Britain’s withdrawal is taking place to a new timetable, what happens next?

If Mrs May has failed to secure Commons support for her Withdrawal Agreement, this is the final day on which the UK can set out its next steps to the European Council, if it wishes to be granted a longer extension. If it does not do so, the UK would leave the EU without a deal.
If the Commons has approved Mrs May’s deal, the UK formally leaves the European Union on this date with a Withdrawal Agreement, entering a transition period during which it will continue to observe EU laws but have no representation in EU institutions.
