State multiculturalism has failed and left young Muslims vulnerable to radicalisation, British Prime Minister David Cameron will say on Saturday, arguing for a more active policy to heal divisions and promote Western values.
Cameron, in a speech to a security conference in Munich, will argue that Britain and other European nations need to "wake up to what is happening in our countries" as well as tackling terrorism through military operations overseas.
"It is time to turn the page on the failed policies of the past," he will say, according to extracts from his speech released by his office.
"So first, instead of ignoring this extremist ideology, we — as governments and societies — have got to confront it, in all its forms."
His comments echo those made by German leader Angela Merkel last year and reflect a push by European governments to better integrate immigrants, given persistent domestic tensions between different cultures.
Aides say his comments on multiculturalism and radicalisation give a direction of travel for future policy, and it remains unclear how the Conservative-Liberal Democrat coalition intend to turn his vision into a reality.
Critis point out that Western foreign policy in the Middle East and beyond, not just a clash of cultures at home, has played a big part in stirring up anti-Western sentiment.
"Under the doctrine of state multiculturalism, we have encouraged different cultures to live separate lives, apart from each other and the mainstream," Cameron will say. "We have failed to provide a vision of society to which they feel they want to belong ... All this leaves some young Muslims feeling rootless."
Some members of Cameron''s centre-right Conservative party, activists in right-wing movements and some voters believe that Britain has become a safe haven for people with anti-Western political views.
Others argue this tolerant approach is the lifeblood of any open and thriving democracy, fearing a crackdown on civil liberties would undermine the kind of society the government was seeking to establish.
Cameron said it was time to replace Britain's "passive tolerance" with an "active, muscular liberalism" to send a message that life in Britain revolves around certain key values such as freedom of speech, equal rights and the rule of law.
"A passively tolerant society ... stands neutral between different values," he will say. "A genuinely liberal country does much more. It believes in certain values and actively promotes them."
