Shadow home secretary Yvette Cooper has accused Gordon Brown's former aide Damian McBride of being "out of control".
Cooper, whose husband Ed Balls was a key Brownite, told Sky News' Murnaghan programme: "I think this is ... about a kind of politics that really is appalling, that we should never go back to.
"It is something that happened some years ago, but I think it's a sign of how much the Labour Party has changed, the very different climate, the very different way in which Ed Miliband is managing things and operating things now, that's a good thing.
"We don't want to go back to the navel gazing of the past."
