LONDON — British Prime Minister David Cameron has ordered an investigation into the Muslim Brotherhood over concerns that the group is planning radical activities in Britain, his Downing Street office revealed Tuesday.

The prime minister’s office confirmed a report in the Times newspaper that said he had asked intelligence agencies to gather information on the “philosophy and activities” of the Brotherhood and its potential threat to the UK.

The government acted following reports that Brotherhood leaders had met in London last year to decide their response to the Egypt crisis, triggered when one of its leading members, Mohamed Morsi, was unseated as president, according to the Times.

The group has since been blamed by Cairo for orchestrating a campaign of violence.

A Downing Street spokeswoman said: “The Prime Minister has commissioned an internal government review into the philosophy and activities of the Muslim Brotherhood and the government’s policy towards the organisation.”

The review is being led by Britain’s ambassador to Saudi Arabia John Jenkins.
