The 11 judges of the Supreme Court are expected to uphold the High Court ruling that there must be parliamentary approval for Article 50.
Supreme Court President Lord Neuberger is due to read out the verdict at 9.30am today at the UK’s highest court in Parliament Square London.
During an appeal hearing in December, Government lawyers battled to overturn a bombshell victory for pro-EU campaigners, led by Gina Miller, at the High Court.
Unless overturned by the Supreme Court, the High Court ruling means that Europhile MPs and peers will get the chance to vote against triggering Article 50 in Parliament.
The verdict is read out at the Supreme Court
The Supreme Court is expected to rule that Theresa May cannot invoke Article 50 alone
What happens next after the Supreme Court ruling?
The Government is widely expected to lose the appeal and is already preparing a bill to pass through the House of Commons and the Lords quickly.
A bill to authorise the use of Article 50 – the legal step that kicks off Brexit talks – is expected revealed by the end of this week, according to the Independent.
Pro-EU MPs and peers will seize on the vote in Parliament as an opportunity to delay, or even derail, the use of Article 50 and Brexit talks.
Europhile politicians are likely to ask for amendments to bill and the addition of conditions on the UK’s exit deal with the EU.
But it is expected that the bill will be passed because politicians do not want to be seen as going against the will of the people.

The Supreme Court Judges.
In December MPs overwhelming voted for a motion saying that Article 50 should be triggered by the end of March 2017.
Mrs May has pledged to invoke Article 50 by the end of March in order to start the two year exit talks from the EU.
If that happens, then Britain is on course to finish EU exit talks and leave the European bloc in 2019.
However, Mrs May has said that the implementation of Brexit will be “phased in” to stop the British economy falling off a cliff edge.
