Excerpt:
Downing Street is to order a crackdown on the Muslim Brotherhood and a network of Islamist groups accused of fuelling extremism in Britain and across the Arab world.
David Cameron launched an inquiry into the Brotherhood earlier this year, prompted by concerns it was stoking an Islamist ideology that had encouraged British jihadists to fight in Syria and Iraq.
Sir Richard Dearlove, the former head of MI6, who is an adviser to the review, is reported to have described it as "at heart a terrorist organisation". The Brotherhood insists it is non-violent and seeks to impose Islamic rule only through democratic change. It has condemned Islamic State in Iraq and the Levant (Isil) and al-Qaeda.
