What does the Supreme Court ruling mean for Brexit?
The Government is already believed to have drafted a short parliamentary bill aimed at authorising Brexit negotiations, which MPs could now vote on as early as next week.
Brexit Secretary David Davis is likely to address the House of Commons later today.
Fears MPs could try and derail Brexit through a vote on Article 50 have been eased after Labour leader Jeremy Corbyn insisted his party would not block Britain’s EU departure.
But it has been reported up to 80 Labour MPs, including some shadow cabinet members, could defy their party leader and vote against Article 50.
The Liberal Democrats and SNP have already stated their MPs will try to defeat an Article 50 bill.
Opposition parties are also likely to try and add amendments to the bill in an attempt to meddle with Brexit negotiations.
The House of Lords is also expected to authorise the start of Brexit talks
House of Commons clerks have told Labour they will not be able to add amendments relating to specific aspects of Article 50 talks, such as forcing the Government to ensure continued access to the Single Market as part of any Brexit deal.
But they could demand the Prime Minister officially publishes her Brexit negotiating aims and force a parliamentary vote on any exit deal early enough so the Government could be sent back to Brussels to negotiate a new one.
Meanwhile, despite previous threats from peers they could delay or even block the approval of Article 50, the House of Lords is also expected to authorise the start of Brexit talks.
The Government has already put peers on notice it could revive efforts to curb the powers of the House of Lords if it hampers Brexit.

Tory MPs have also suggested swamping the House of Lords with hundreds of Brexit-backing peers should it vote against Article 50, while there have also been calls to scrap the upper chamber completely if it defies the EU referendum result.
