British Home Secretary Amber Rudd suggested that the he may return to Britain amid talks between officials in the United Kingdom and United States.
The Government has previously wanted Alexanda Kotey and another member, El Shafee Elsheikh to face justice in the United States for partaking in crimes that include the beheading of hostages.
London born Kotey and Elsheikh were the last two members of the so-called “The Beatles” to be detained by Syrian Democratic Forces (SDF) in eastern Syria.
They are among foreign fighters captured during advances that saw all of Isis’ major strongholds in the country retaken by government and opposition forces.
The anti-Isis coalition expect the captured fighters to return to their home countries for disposition.
Tobias Ellwood, a parliamentary under secretary of state at the Ministry of Defence, has argued that the men should be tried at the International Criminal Court but it can only act when countries are “unable or unwilling” to exercise their jurisdiction.
Lord Carlile, the former Independent Reviewer of Terrorism of Legislation, said a British trial was the “proper forum” and the prospect has been supported by their victims and relatives.
Kotey was wanted for involvement in the execution of hostages including the American journalist James Foley and British aid workers David Haines and Alan Henning.
He among others were declared “specially designated global terrorists” for their roles in the group, which was responsible for beheading more than 27 hostages and torturing many more.
The ringleader of “The Beatles’” Jihadi John, whose real name was Mohammed Emwazi, was killed in 2015 by a drone strike and the fourth militant in the cell, Aine Davis, has been jailed for terror offences in Turkey.
Kotey, who is of Ghanaian and Greek Cypriot origin grew up in Shepherd’s Bush, West London. He is believed to have converted to Islam in his early twenties, and left two young children in Britain when he travelled to Gaza in 2009 as part of an aid convoy organised by former Labour and Respect MP George Galloway.
