Following the massacre in Norway and amid concerns over contacts between the killer and supporters of the English Defence League, the Government is reviewing its policing of right-wing terrorism.

James Silver examines far right extremism in the UK and reports from some areas with large Muslim populations where fears of 'Islamistion' are fuelling tensions between communities. We hear of the targeting of gay men in East London, as well as attacks on a mosque in Luton.

Is there a disenfranchised minority who feel they have no political voice and are now looking to networks like the English Defence League? And are the EDL right to suggest that the threat of anti-Muslim terrorism in the UK could grow?

Please note there has been a change to this programme since the original broadcast because of an erroneous reference to the English Democrats.
