With reports that as many as 2,000 British jihadists are fighting alongisde Islamists militants in Syria and Iraq, radicalisation, and the demolition of it, has become increasingly important.
Drunk on fundamentalist ideology, some British Muslims have travelled to wage jihad (the Arabic word for "struggle" or "resisting", which has come to be associated with terrorist activity) in the Middle East for groups like al-Qaida affiliate Jabhat al-Nusra. The focus at home is now on how to sober them up if they come back – or, preferably, before they have had a chance to leave.
Charlie Winter, researcher at anti-extremist think tank Quilliam, talks through the five crucial steps involved in de-radicalising Islamic extremists in the UK.
