Prime Minister Gordon Brown's popularity has slumped to a record low, but a change in leader will not help the ruling Labour Party win the next election, according to an opinion poll published on Friday.A YouGov poll in The Daily Telegraph said only 15 percent of people questioned believed Brown was "up to the job".
It said this was the lowest approval rating for a prime minister since John Major in 1995, two years before his Conservative government suffered a crushing election defeat that has ushered in 11 years of Labour rule.
