Abu Qatada has been described as al Qaeda's spiritual leader in Europe, the most significant extremist preacher in the UK and "a truly dangerous individual".
Since the September 11 attacks, Qatada has challenged and thwarted every attempt by the UK Government to detain and deport him.
Here is a timeline of key events in his long-running battle against deportation.
- 1993 - September 16 - The Jordanian father of five, real name Omar Mahmoud Mohammed Othman, claims asylum when he arrives in Britain on a forged passport.
- 1994 - June - He is allowed to stay in Britain.
- 1999 - April - He is convicted on terror charges and sentenced to life imprisonment.
- 2001 - December - Qatada becomes one of Britain's most wanted men after going on the run from his home in west London.
- 2002 - October - He is arrested by police and detained in Belmarsh high-security jail.
- 2005 - March - Qatada is freed on conditional bail and placed on a control order.
- 2008 - April - Court of Appeal rules that deporting Qatada would breach his human rights.
- 2009 - February 18 - Qatada can be deported to Jordan to face a retrial on the terror charges.
- 2013 - June 18 - It is confirmed the King of Jordan has approved the mutual assistance treaty with the UK.
Abu Qatada has finally left Britain to face terror charges in Jordan after nearly a decade long legal battle to deport the radical cleric.
Abu Qatada has been deported from the UK to Jordan to stand trial on terrorism charges after nearly 10 years of legal disputes.
With reports that Abu Qatada will leave the UK early on Sunday, it looks like Theresa May has finally won the battle to deport him.
