It looks like we're slowly moving towards a game plan and, in spite of government lawyers advising that the PM has prerogative, there will be a vote in both Houses - Commons and Lords.
There's no need for MPs to vote on starting Brexit, government lawyers advise - but minister says Britain won't leave the EU without Parliament voting on withdrawal process. Cabinet Office minister Oliver Letwin, tasked with setting up the Government's Brexit unit, said the Government's legal advice agreed that the Prime Minister will be able to trigger Article 50 - the legal process for leaving the EU - without first securing parliamentary approval. But he acknowledged there were 'conflicting views' over whether Article 50 can be invoked under prerogative powers or required parliamentary approval and predicted it would end up in court. And he said the row was 'academic' because the withdrawal process will also involve either repealing or amending the 1972 European Communities Act, which will require debates and votes in both Houses of Parliament.
