Britain's Prime Minister ordered an investigation into the Muslim Brotherhood Tuesday over "concerns that the group is planning radical activities" from the UK base, according to Agence France Presse.
One of the PM's spokeswoman told the UK-based Times newspaper: "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."
Intelligence sources confirmed the spokeswoman's comments, saying that they were told to investigate the Brotherhood and its "potential threat to the UK."
The review, which is being led by Britain's Ambassador to Saudi Arabia John Jenkins, will include an investigation over whether the Brotherhood is connected to the tourist killings in Egypt's Sinai in February. The group has repeatedly denied connections to the attack, which was claimed by Al Qaeda-linked Ansar Bayt Al Maqdis.
The review will also investigate whether prominent members of the group have been meeting in Britain to plot their response to political developments in Cairo, according to the Times.
"Given the concerns about the group and its alleged links to violent extremism, it's absolutely right and prudent that we get a better handle of what the Brotherhood stands for, how they intend to achieve their aims and what that means for Britain," said the Downing Street spokesperson.
According to the Guardian, Britain may "possibly" follow Saudi Arabia and Egypt in declaring the Brotherhood a terrorist group, but the move does remain "unlikely."
