A government spokesperson said:
The British people voted to leave the EU, and the government will deliver on their verdict – triggering Article 50, as planned, by the end of March. Today’s ruling does nothing to change that.
It’s important to remember that Parliament backed the referendum by a margin of 6 to 1 and has already indicated its support for getting on with the process of exit to the timetable we have set out.
We respect the Supreme Court’s decision, and will set out our next steps to Parliament shortly.
