Speaking outside the Royal Courts of Justice after the ruling, Gina Miller said she was “very disappointed with the judgment”.

She added: “We feel it is absolutely vital that Parliament should be sitting. We are therefore pleased that the judges have given us permission to appeal to the Supreme Court, which we will be doing, and they feel that our case has the merit to be handed up.

“Today, we stand for everyone. We stand for the future generations and we stand for representative democracy.”

Ms Miller added: “To give up now would be a dereliction of our responsibility. We need to protect our institutions. It is not right that they should be shut down or bullied, especially at this most momentous time in history.

“My legal team and I will not give up our fight for democracy.”
