Britain's government will outline a revised strategy to tackle home-grown terrorism amid revelations that millions of pounds spent on overseas anti-extremism projects failed to steer young Muslims away from violent extremism.

The government is expected to admit that its costly and controversial initiatives did not produce security benefits for the U.K. and could even have helped fund groups that promote hardline beliefs.

The revised approach will focus on identifying extremist threats in prisons, universities and the health service. The fresh strategy, spurred by a review of Britain's anti-extremism project amid concerns it was not working, will also suggest measures to limit the scope of the Internet in fostering radicalization.
