Royal Marine Alexander Blackman, who was found guilty of murdering an injured Afghan fighter last year, has lost his challenge against his conviction at the Court of Appeal in London.
Although the Court Martial Appeal Court rejected a conviction challenge by Sergeant Alexander Blackman, three leading judges cut his minimum term from ten to eight years - the least time he must now serve before becoming eligible to apply for parole.
A Royal Marine convicted of murdering an Afghan insurgent will have to wait to find out whether his appeal has been successful.
Three judges at the Court Martial Appeal Court in London will now give their decision at a later date.
Sgt Alexander Blackman was found guilty by a seven-man court martial board last November and sentenced to a minimum of 10 years in jail.
Lawyers for Sgt Blackman told the court the verdict should not stand because the court martial process did not demand the same level of proof as a normal criminal trial.
Anthony Berry QC also argued that the court martial board had not taken into account the "tremendous stresses" of combat which had caused Sgt Blackman "briefly to lose his head".
The wife of the marine convicted of murder has told the Daily Telegraph she is sure he could go back in time and undo that "moment of madness."
Sgt Alexander Blackman's wife said: “He’s held his hands up. What he has not done in my eyes is commit murder.
"He genuinely thought, and I have absolutely no reason to disbelieve him, that that insurgent was already dead.
“He should not have discharged his weapon into him – it was the madness of the moment – and he sure as hell wished he hadn’t either but he is not a murderer.”
Claire Blackman also revealed: “I am sure Al would love to meet Dr Who, travel back in time and undo that moment. “He can’t undo it and he’s ashamed of it but I still don’t think it should have led to where we are now.”
The wife of a Royal Marine jailed for murdering a wounded Taliban fighter has said he is not a killer, in an interview with the Daily Telegraph.
Sergeant Alexander Blackman, known as Marine A, was jailed for life, with a minimum of 10 years, by a court martial last week. He was caught killing the man on his colleague's helmet camera.
“He’s been convicted of murder but everything that defines Al points me and everyone who knows him in completely the opposite direction – he is not made that way", Claire Blackman told the paper.
She added: “If you ask someone what murder is in this country they might say someone stabbing a little old lady in the high street.
“Death on active service in a war zone in somewhere like Afghanistan is, sadly, an everyday occurrence. I can’t really imagine the horror or the pressure those lads were under.”
