The extremist, who cannot be identified, was granted the taxpayer funds even though he was described in court as the ‘very model of a modern Al Qaeda terrorist’.
The payments are particularly alarming following the atrocities in Westminster, Manchester and London Bridge that cost 35 innocent lives.
And the election result has cast doubt on Theresa May’s pledge to tear up the Human Rights Act in cases where it blocks the deportation of extremists.
The terrorist who has been granted legal aid came to England illegally in the months after the September 11 attacks as a ‘sleeper agent’ for a group linked to Al Qaeda.
The Jordanian claimed asylum by pretending to have fled the Middle East in fear of his life.
The claim was dismissed and he should have been deported. But he managed to stay and evade authorities simply by using a fake name. He was given a council house with his wife and claimed at least £100,000 in benefits.
The terrorist was arrested after a bank tipped off police about unusual activity on his account.
On his home computers, police found terror manuals detailing how to carry out bombings, with guidance on ‘suitable targets’ including airports and nightclubs.
He also had instructions on setting up a terror cell linked to Al Muhajiroun, the proscribed group. It is led by Anjem Choudary, the jailed hate preacher, and was supported by Khuram Butt, one of the London Bridge murderers.
The jihadi was convicted of six counts of possessing material for a purpose connected with terrorism and sent to jail.
A judge said his crimes were some of the most serious before the courts. But since completing his sentence, the Government has failed to deport him.
He was refused refugee status by the Home Office but has launched continued appeals through the courts.
He has gained from £253,000 in taxpayer-funded legal aid since his arrival in the country, according to figures released to the Daily Mail under the Freedom of Information Act.
