Anjem Choudary’swife is being investigated over allegations that she has been running an extremist female cell in east London.

The 42-year-old mother of five was caught on camera apparently praising Islamic State of Iraq and the Levant (Isil) as she preached to Muslim mothers and young children at a secretive meeting.

Rubana Akhtar, who is the self-declared leader of the women’s wing of her husband’s banned Al-Mouhajiroun (ALM) movement, was also recorded apparently making anti-Semitic remarks, including referring to “filthy Jews”.

Going by the name Umm Luqman, she delivered a weekly two-hour lecture to a group of female followers in London touching on many of her husband’s favourite topics.
