(BBC) The government does not record the number of people prosecuted for terror offences after returning to the UK from Syria, an official report says.
The data is held neither “officially or unofficially,” an annual review by the independent reviewer of terrorism legislation, Jonathan Hall QC, says.
Figures previously provided to Parliament by ministers later had to be clarified.
Mr Hall’s report instead relies on BBC News research on the subject.
It is known that hundreds of people have returned to the UK after joining terrorist groups in Syria but the cumulative figure given in public is ambiguous.
