Protests are planned across the country on the eve of the government’s first refugee deportation flight to Rwanda.
The Court of Appeal this afternoon ruled that the flight could take place, deciding not to overturn a ruling made last week in the High Court.
Eleven asylum seekers are due to be on board, down from an original number of over 100, with the flight set to leave from Stansted at 10.30pm on Tuesday night.
In the hours before the protest, campaigners waited to hear a verdict from the Court of Appeal, which is due to rule on an attempt to block the flight.
Shortly after 4.30pm, Lord Justice Singh dismissed the appeal, meaning the flight is free to go ahead.
