This is not surprising. After all, the British authorities, like all Western authorities, don't even know what questions to ask in order to screen for this sort of thing. "Radical past of top Whitehall Islamic aide," from the [1] TimesOnline, with thanks to Anon:

DISTURBING details have emerged about the radical background of the chief adviser on Islamic affairs at the Foreign Office.

Mockbul Ali, a 26-year-old civil servant, was involved in a Muslim student group that has published material supporting Palestinian female suicide bombers.

The Union of Muslim Students (UMS), which has been repeatedly praised by ministers as a paragon of moderate Islam, also carried articles in its newspaper by Sheikh Yusuf al-Qaradawi, a Qatar-based preacher banned from entering America.

Leaked documents show that since joining the Foreign Office Ali has argued for Qaradawi to be allowed into Britain and played a part in sending Sharif Hasan al-Banna, president of the UMS, to Islamic conferences in Indonesia and Nigeria at taxpayers’ expense.
