(BBC) The Liverpool bomb attacker was a failed asylum seeker who had been refused permission by judges to appeal to stay in the country.
It had been reported — but unconfirmed — that Emad Al Swealmeen lost his asylum claim as long ago as 2014.
The BBC has now confirmed he made a legal attempt to gain permission to stay in the UK, but it was rejected without being considered in court.
It raises questions as to whether the Home Office then sought to remove him.
The Upper Tribunal of the Immigration and Asylum Chamber, a national court that deals with appeals, told the BBC that Al Swealmeen had sought to lodge an appeal after he had lost his case in a lower court that reviews Home Office decisions.
