Excerpt:
Scotland Yard is to enlist terrorist convicts and other former extremists in a new bid to combat Islamic State propaganda and stop more Londoners being lured to fight in Syria.
Chiefs want to develop new "counter-narratives" to challenge Islamist ideology. The plan has already involved using militants who have returned after travelling to join conflicts abroad.
Police say their attempts to stop the spread of radical ideas are receiving "significant" help from these people — and they are "desperate" to recruit more. Met officers are also seeking to "turn" terrorist convicts freed from sentences, and others still in jail, in a further bid to find new ways to persuade young Londoners to shun extremism.
