With the first flight on the deportation schedule scheduled for Tuesday night, the activists also promised to target the Spanish charter airline believed to have provided the aircraft. A Supreme Court justice ruled on Friday that he would not stop the first deportations to Rwanda of people who had arrived in Britain via unofficial routes, but an appeal against his decision is expected on Monday. Hundreds of people, including representatives of campaign groups and religious organizations, gathered in St Peter’s Square in Manchester on Sunday to protest the flight, which was described by speakers as “indecent”. horrible. More protesters gathered outside the Brook House evacuation center near Gatwick, holding placards. Mark Serwotka, general secretary of the PCS union, which accounts for more than 80% of Border Force personnel, said he hoped the appeal would be stopped, adding that Priti Patel, the interior minister, should not implement the policy before its legal position was fully tested. He told Sky’s Sophy Ridge on Sunday: “Imagine being a civil servant now in the Home Office who goes to work because you want to see a human migration system where people are treated fairly and we comply with our international obligations. “Imagine being told to do something on Tuesday, that in July then it is considered illegal. That would be a horrible situation. “I mean, if Priti Patel had any respect, not only for the desperate people who come to this country, but also for the workers she employs, she would not have asked any of them to take part in any deportation of any asylum seeker. “at least until these cases are heard in court for the full legitimacy of the crisis, which will take place in July.” The Interior Ministry has said it is dealing with staff, but stresses their responsibility to civil servants under the Civil Service Code to serve the government of the time. A Spanish airline is considered to be taking over the deportation flight on behalf of the Ministry of the Interior.

The ruling will not deter individual refugees from further legal challenges to their removal or judicial review of the policy, which Swift said could take up to six weeks. The policy is intended to prevent people from using informal routes, such as crossing the Channel in small boats, to enter the UK and seek asylum. The number of people doing it has not yet been reduced, but Downing Street says the impact will only be seen when the policy is fully operational. Critics say the relatively small number that could be sent to Rwanda would not deter people and that the fact that people with children would not be deported would be a mere incentive for minors to board boats.
