UKIP Leader Paul Nuttall MEP has said the Supreme Court's decision to deny the Government's appeal and insist that Parliament vote on the triggering of Article 50 would not jeopardise Brexit.
"This decision is hardly a surprise but in the end it will make no real difference," Mr Nuttall said.
"The will of the people will be heard, and woe betide those politicians or parties that attempt to block, delay, or in any other way subvert that will.
"Other than making clear that this is a decision of the whole United Kingdom, rather than its constituent parts, what we can clearly see is that it will embolden those who rail against the decision of the people. It may give heart to those in the EU, used as they are to ignoring their own people, to attempt to play hard ball in the negotiations.
"But in the end I am convinced that though this skirmish has been lost in the courts, the war will be won."
