The father of a Royal Military policeman killed in Iraq has launched a campaign to unseat Tony Blair in the General Election.
Reg Keys, aged 52, called on the Conservatives and Liberal Democrats not to field candidates in the Prime Minister's Sedgefield constituency so that he had a clear run.
He also asked ex-MI5 officer David Shayler, who has announced he will stand in Sedgefield, to withdraw.
Mr Keys launched his campaign at the studios of Roxy Music star Brian Eno in London and travelled to Sedgefield yesterday afternoon.
The musician, who is financing Mr Keys' efforts, is currently out of the country.
Mr Keys' son Lance Corporal Tom Keys, aged 20 and originally from Solihull, was one of six Red Caps killed by an Iraqi mob as they manned a small police station in Al Majar Al Kabir on June 24 2003.
He said his campaign was to achieve "justice" for his son.
"We are going to speak to the other candidates this week to see if we can have an arrangement," he said.
Mr Blair's majority is a massive 17,000, but Mr Keys said: "I think we can make a big dent in that and I think I can win. I'm not backing off or moving away, I've made the ultimate sacrifice for this campaign, I've lost my son.
"When Tony Blair visited the victims of the Omagh bombing he said: 'I have seen sights today that will haunt me for the rest of my life. If anything happened to one of my children I would go mad with grief.'
"How does he think those families of dead Iraqis feel?
"How does he think I felt when I dressed my son for his funeral, combed his beautiful blond hair and tried to avert my vision from the side of his face that had been blown off?
"I'm coming for you Mr Blair, but I'm going to do it in a civilised way."
Mr Keys, a former ambulance driver, challenged the Prime Minister to debate with him on TV.
And he read a poem sent to him by a serving British soldier about his guilt at shooting an Iraqi. The poem, called The Enemy included the lines: "When I left you alone back there, please don't think I did not care.
"It's just that I was scared of you, I wasn't sure what I should do."
A week ago, the Conservative candidate in Sedgefield announced he was standing down.
Danny Kruger was quoted in a newspaper as saying that the Tories were planning a "period of creative destruction" in the public services.
The party claimed his remarks had been taken out of context
