Nick Clegg has backed the initiative to stop Brits from joining the Syria conflict, warning that the return of radicalised fighters from Syria was "now one of the biggest security threats we face as a country".
"I don't think we should under-estimate the gravity of this now," the Deputy Prime Minister said during his weekly phone-in on LBC radio.
"The security threat to us as a country - on British streets, British towns, British cities, British communities - from people going to Syria and coming back radicalised with violent intentions is now one of the biggest security threats we face as a country.
"It is something the Prime Minister, myself and other members of the Government are very focused on so of course I support the work of the security services and the police."
