The High Court has ruled that Theresa May cannot bypass parliament and trigger Article 50 without a vote from MPs.
That means that, for now, Britain's exit from the European Union is on hold.
In response to this, Michael Zander QC, Emeritus professor of the Law at the LSE, wrote in the Times that neither the Lords nor the Commons would willingly vote against a Brexit. But that could change.
The Government has been given permission to appeal the decision in the Supreme Court and, in irony of ironies, could even take it to the European Court if it doesn't go its way.
So will Brexit still happen? If the Supreme Court upholds the High Court's decision then it will be down to MPs to decide.
It's then up to MPs whether they want to go against the will of the 52 per cent.
