A rebel Labour member of the Welsh Assembly is to fight the General Election as an independent, despite originally withdrawing from the race after being diagnosed with a brain tumour, he announced today.
Peter Law will stand in the safe Labour seat of Blaenau Gwent, which he represents in the Assembly, after a long-running row over women-only shortlists.
The party chose its candidate, Maggie Jones, from such a list despite local opposition.
Mr Law said two weeks ago he would stand, only to reverse the decision after being diagnosed with the tumour. He has now received treatment and says he is well enough to campaign.
His decision to quit Labour also deprives the party of its one-seat majority in Cardiff Bay, causing a political headache for First Minister Rhodri Morgan.
Mr Law said: "I have decided I will stand for the General Election in Blaenau Gwent. I made a contract with the people 18 months ago when they imposed all-women shortlists.
"I've been encouraged by the many prominent people in Blaenau Gwent who have said they will work for me.
"The point is the people of Blaenau Gwent have been used and abused and I am ashamed that the Labour Party which I was a member of should have done that."
He said the last two weeks had been "difficult" for his family but he had still decided to stand. He said he felt "cleansed" after leaving Labour.
"It's not the Labour Party I joined. It's veered to the right," he said.
Blaenau Gwent is home to one of the largest parliamentary majorities in the UK.
Retiring MP Llew Smith had a majority of 19,313 at the 2001 poll. The seat has been represented by former Labour leader Michael Foot and NHS founder Aneurin Bevan.
