Jim Murphy’s mansion tax raid on London to fund nurses in Scotland has descended into an almighty slanging match with Diane Abbott. The Hackney MP couldn’t even remember the Scottish Labour leader’s name on Wato today:

“I am very surprised John Murphy is making these boasts… Jim Murphy can’t surely mean he is going to expropriate money from London to Scotland… he is jumping the gun in an unscrupulous way.”

Murphy hit back:

“It’s hard to take this argument seriously when she can’t even remember my name… I am leader of the Scottish Labour party, not Diane. I don’t have to consult Diane Abbott… I don’t have to clear things with Ed Miliband.”

Shots fired!
