UK's anti-terror chief fears rights group boycott threatens Prevent review

Neil Basu says move to protest appointment of William Shawcross could harm process

Britain's best chance of reducing terrorist violence risks being damaged amid a huge backlash to the government's choice of William Shawcross to lead a review of Prevent, the country's top counter-terrorism officer has told the Guardian.

Assistant commissioner Neil Basu's comments came after key human rights and Muslim groups announced a boycott of the official review of Prevent, which aims to stop Britons being radicalised into violent extremism.
