Veteran Labour MP Dennis Skinner has been voted off the party's national executive committee (NEC) by fellow MPs to the fury of some colleagues.

The 82-year-old left-winger, who has been in the Commons since 1970, lost his place on the NEC to former minister John Healey in a ballot of the Parliamentary Labour Party, sparking heavy criticism from some supporters.

Jim Murphy, the East Renfrewshire MP and shadow international development secretary, wrote on Twitter: "Really sorry to hear that Dennis Skinner was voted off Labour's NEC", adding: "A brilliant MP & good friend. Hopefully he'll make NEC comeback."

Paisley & Renfrewshire North MP Jim Sheridan tweeted: "Have lost a powerful voice for the working classes at the heart of the Party. A sad day for Labour."

Shadow cabinet office minister and NEC member Jon Ashworth posted: "So sorry that Dennis Skinner (who I voted for) not re-elected. He will be a big loss."

MP John Mann said the vote showed "naive political immaturity in [the] Parliamentary Labour Party in knocking Dennis Skinner off NEC in election year."

Labour leader Ed ­Miliband's office dismissed suggestions that Mr Skinner had been the victim of an organised campaign by the leadership.
