British PM David Cameron has asked MI5 and MI6 to investigate the Muslim Brotherhood amid fears the group is co-ordinating extremist activities from the UK.

The intelligence agencies are to assess the scope of the Islamist group’s operations in the UK after concerns were raised that it is running its international operations from a flat in Cricklewood, north London.

The internal Government review aims to establish the “philosophy and activities” of the group, which came to prominence for its role in the Arab Spring and the overthrow of Hosni Mubarak in Egypt.

Muslim Brotherhood president Mohamed Morsi was removed from power by the Egyptian army in July and last month 529 members of the group were sentenced to death.

Egypt and Saudi Arabia clam London has now become, a central point for meetings where the group can plan its international strategy, According to a report in The Times newspaper.

Cairo claims the Brotherhood has been behind a campaign of violence in Egypt, including a bus bomb in February, which killed three South Korean tourists.

PM David Cameron is thought to have come under pressure from Gulf states to take action, Including Potentially adding the group to the list of Organisations banned in the UK because of their links to terrorism.

However, The Times quoted officials as saying it was “possible but unlikely” it would join the proscribed list.

The review is being led by Sir John Jenkins, Britain’s ambassador to Saudi Arabia, which has also declared the Brotherhood a terrorist organisation.

The United Arab Emirates, Russia, Syria and Egypt also consider the group a terrorist organisation.

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.”

Mr Morsi and many other senior figures are imprisoned facing trial in Egypt following the military takeover, which resulted in protests that killed at least 1,000 people.

The Brotherhood, which was founded in Egypt in 1928 and runs on a political and charitable model, maintains it is peaceful. However, some fear that fringe elements could have links with violent extremists.

A spokesman told The Times it would co-operate with the British Government review.

Asked about the investigation on his LBC radio programme, London Mayor Boris Johnson said: “I’m afraid I can’t give you any details about that investigation and nor would you expect me to.

“As it happens, I don’t know very much about this particular case, but even if I did know, it would not be something I would be commenting on.

“When you look back at 7/7 and some of the challenges – the airline plot, some of the challenges that the counter-terrorist units have had to face – I think it is amazing that, touch wood, they have done an absolutely unbelievable job.”
