In a letter seen by BBC London, the commission says it is beginning a statutory inquiry into the Masjid-al-Tawhid mosque in Leyton.

It comes as liberal Imam Dr Usama Hasan resigned from the mosque following death threats for teaching about evolution and women's rights.

The mosque has declined to comment.

In the letter, the Charity Commission states the investigation will look at whether the Masjid-al-Tawhid Trust "allowed individuals with potential links to terrorist organisations to use the charity to promote and/or express extremist views; and/or the trustees have taken appropriate steps to safeguard the reputation of the charity."
