Home Office thwarted return home of Isis suspect Jack Letts

Letts was disillusioned in Syria but his case officer was told to 'back off' by the government

British Islamic State fighter Jack Letts, whose parents were convicted of funding terrorism, wanted to return to the UK, but the Home Office pulled the plug on attempts to rehabilitate him.

The 23-year-old - known as "Jihadi Jack" - who joined Isis as a teenager, had discussed leaving Syria in 2016 with a counter-radicalisation expert until the UK government took him off the Letts case, the Observer has learned.
