Labour leader Ed Miliband has paid tribute to former energy minister Malcolm Wicks, who died today aged 65.
The Croydon North MP, who had been fighting cancer, was praised as a "thoroughly decent, intelligent and compassionate man" whose death left a "huge hole" in the party.
"He was a brilliant energy minister, he was a deep thinker about welfare and pensions, and Labour to his core," Mr Miliband said.
"Malcolm was also a dedicated constituency MP, always putting the needs of his Croydon constituents first. He was a brilliant campaigner.
"I have lost a wise confidant and most importantly a dear friend and the Labour Party has lost one of its sharpest thinkers. Our thoughts go to Malcolm's wife, Margaret, and his family."
