Over 100 people attended a meeting in Bury last Saturday to launch the Bring Danny Home Campaign.
Next Sunday, proceedings will start in Iraq that could lead to the ex-soldier from Manchester, Danny Fitzsimons, facing the death penalty. He faces a murder trial after shooting dead two other mercenaries in Iraq.
Sue Glenton, Lance Corporal Joe Glenton’s mother, spoke in support of the campaign.
ArmourGroup, the British Company that took £25 million to guard Baghdad Airport employed Danny without making proper checks on his health.
The first stage of the campaign aims to “put ArmourGroup who made $9.5 billion last year on trial”.
Campaigners have plans to picket an office of ArmourGroup, or the parent company Group Four.
