The prime minister insisted asylum seekers will be sent to the east African nation in 10 to 12 weeks “come what may” and that regular trips will take place over the summer.But he faced an agonising final hurdle of ping-pong between MPs and the House of Lords, and the upper house will spend the evening trying to exact two key amendments. MPs and campaigners warned that Mr Sunak’s flagship policy, if successfully passed, could still be set back by legal challenges from individuals, as well as the civil service union which is concerned about breaching international law.Labour condemned the hundreds of millions of pounds already spent on the scheme as an “extortionate gimmick”, while former home secretary Suella Braverman said so few people would actually end up in Rwanda that it would not work as an efficient deterrent.Kicking off a long day of political wrangling, Mr Sunak threw down the gauntlet to peers in a surprise press conference on Monday, saying: “Parliament will sit there tonight and vote, no matter how late it goes; no ifs, no buts, these flights are going to Rwanda.”Lords have been trying to force the government to exempt Afghans who supported British troops overseas from being deported to Rwanda. They had also pushed an amendment that would make sure a monitoring committee assesses Rwanda to be safe before flights take off. The government has so far refused to cave to pressure and include the changes to the bill. MPs rejected both amendments in their first vote on Monday evening. Labour peers will rally this evening in support of the suggested amendments, leaving the cross-bench peers with the power to further delay the bill or let it pass.
