A British Muslim convert once suspected of being a member of an Islamic State (IS) death squad dubbed The Beatles has pleaded guilty to terrorism charges.

Aine Leslie Davis, 39, was deported from Turkey last August after serving a seven-and-a-half year sentence for membership of IS, an armed terrorist group.

On his arrival at Luton airport, he was detained by British counter-terrorism police and charged with three offences.

On Monday, Davis returned to the Old Bailey and pleaded guilty to possession of a firearm contrary to Section 57 of the Terrorism Act 2000, and two charges of funding terrorism between 2013 and 2014.
