 Britain's Prime Minister Rishi Sunak has condemned the right-wing populist Reform UK party after some campaigners were filmed by an undercover reporter making racist and homophobic remarks. The footage was obtained secretly by Channel 4 News in Clacton in south-east England, where the party's leader, Nigel Farage, is standing in next week's election. One volunteer, identified as Andrew Parker, talked about shooting illegal immigrants.
