Labour risks being shut out of government for almost a decade if it continues to be seen as "too Remain", an ally of Jeremy Corbyn has said, as a pro-Europe former minister warned that the party must "heed the warning" from the local elections.
Steve Howell, Mr Corbyn's former deputy director of strategy, said "Brexit is undoubtedly a big factor in how some people voted" in Thursday's poll, which saw Conservatives make gains across the country.
His comments came as Caroline Flint, the Labour ex-Europe minister, warned that the party risked "alienating many traditional Labour voters" if it "fails to stand by the 2016 vote".
