By Elizabeth Piper and Andrew MacAskillLIVERPOOL, England (Reuters) -British Prime Minister Keir Starmer called on his party on Sunday to stop “navel gazing” and unite to defeat Reform UK, accusing the populist party of planning to launch a “racist policy” of mass deportations if it wins power. “I’m saying we have got the fight of our lives ahead of us, because we’ve got to take on Reform. We’ve got to beat them and so now is not the time for introspection or navel gazing,” he told BBC news. Starmer defended his government’s efforts to tackle illegal immigration, which is one of the main concerns of British voters, describing Farage’s plan to deport refugees who had settled in Britain as “racist”. The polling firm Ipsos said his approval ratings have fallen to the lowest level of any prime minister since it started collecting the data in 1977.
