May's speech to set out her Brexit vision
Theresa May will make her highly-anticipated major speech on Brexit on Tuesday, a Number 10 source has confirmed.
The Prime Minister will be under pressure to spell out a strategy ahead of triggering formal divorce negotiations, which she has promised by April.
Reports have suggested Mrs May will commit to pulling out of the single market if the European Union fails to make concessions on the free movement of its citizens, although they have been dismissed as speculation.
Foreign Secretary Boris Johnson and Brexit Secretary David Davis are contributing to the content of the address.
The speech will come as the Prime Minister prepares to trigger Article 50 of the EU treaties to begin the formal process of leaving the bloc.
Meanwhile, the Supreme Court is due to rule this month on whether Mrs May has the authority to invoke Article 50 without the prior consent of Parliament.
