THE twin brother of a soldier killed in Iraq has vowed to continue his fight for justice after being told he will never see Tony Blair in the dock.

Mike Wilson is heading up a last ditch attempt for the 179 families of servicemen and women who died during the invasion – by launching a petition calling for Parliament to step in.

Among them was his sibling Lance Corporal David Wilson, of Spennymoor, who died at the age of 27 from a gunshot at Basra airbase in December 2008, weeks after becoming a father.

This week the legal team behind the Iraq War Families Campaign Group (IFCG) concluded legal action against state officials would not be possible.

In a statement, the group said: "Regrettably, they (the lawyers) have been obliged to conclude that the combination of the UK’s underlying constitutional arrangements, and recent significant judgments of the higher courts, have closed off any possibility of civil proceedings being commenced."

The findings come following repeated failed private prosecution attempts, including against the former Prime Minister.

Among its findings, the report concluded: the UK joined the invasion before exhausting all peaceful options; that there was no imminent threat from Saddam Hussein whilst “flawed” information was followed over the alleged weapons of mass destruction.

Lawyers for the IFCG have informed the group that even if state officials knew they were acting in violation of their constitutional duties and were therefore reckless as to the damage that would cause, such breaches are not actionable in a court of law and can only be punished by Parliament.

As a result Mr Wilson, of Darlington, will this send live a Government website petition demanding Parliament overturns decisions made in the courts preventing families from pursuing civil action, while using its own powers to hold the former Sedgefield MP to account.

The 36-year-old said: "We've had notifications from lawyers that Tony Blair has been made immune from civil proceedings because of recent judgements.

"He needs to be held to account for what he has done - nobody should be immune.

"He has destroyed 179 families who have lost people on the basis of a lie. This has made us more determined."

The petition will need 100,000 signatures to be debated in the House of Commons while the IFCG, which represents about 30 families, will also write to Theresa May.

Responding to the Iraq War Inquiry in 2016, Mr Blair accepted responsibility and expressed “sorrow, regret and apology” over mistakes made in the planning and conduct of the war, but insisted the decision was made “in good faith”.
