Last night MPs voted to take control of the Brexit process, and indicative votes will be held on Wednesday to endeavour to find a majority view in Parliament as to what form Brexit should take. This cannot affect the withdrawal process but can only give guidance as to the future negotiation after withdrawal of the relationship between the EU and the UK.
The PM stated she would introduce a statutory instrument to amend ‘exit day’ in the EU Withdrawal Act 2018 and this would be laid on Wednesday, so no exit on 29 March. Mrs Leadsom has now stated that this will take place after the indicative votes on Wednesday.
A further extension beyond 12 April can only be granted if the PM asks for one. If the withdrawal agreement is passed then the extension would be to 22 May. If not then the UK would leave the EU on that date. It is possible that this might be forestalled by a vote of no confidence in the government followed by the appointment of a temporary PM with the mandate of requesting a further extension and ensuring the UK participates in the elections to the European Parliament on 23 May.
