Genuine change for Labour: Miliband
Ed Miliband has insisted the Labour Party was embarking on "real, deep, genuine change" to reconnect with disenchanted voters.
The party's humiliating defeat in the Bradford West by-election was a reminder of the "scale of the task" facing Labour after it was rejected in the 2010 general election, he said.
"You might think the Government's failure to bring about change will be good for Labour," he said in a speech in Derby.
"It certainly didn't turn out that way in Bradford West two weeks ago. The uncomfortable truth for Labour is that people turned to a protest party rather than to us."
The Labour leader said: "People turning away from an unpopular Government doesn't automatically mean they turn to Labour."
Mr Miliband insisted David Cameron's changes to the Conservative Party were only "skin deep" and a lesson to Labour as it seeks to win back power.
"To be trusted to deliver change, we will not make the same mistake as David Cameron," he said.
"Our party is recognising the real changes we need to make. Not hugging a husky then betraying the environment. Or hugging a hoodie and then cutting youth services. Real, deep, genuine change, infusing our party, our ideas and our organisation."
Mr Miliband said it was "not good enough" for Labour to point to the Government's "failure" but had to show that the party is "rooted in communities".
"The next election will be about us as much as them," he said. "It is a changed Labour Party that is standing in these local elections and we will continue to change."
