Jeremy Corbyn has been condemned for making the salute of an Islamist organisation which was described by a Government inquiry as “counter to British values and democracy”.

The Labour leader was pictured making the four-fingered Rabbi’ah sign, a symbol of the Muslim Brotherhood, during a visit to Finsbury Park mosque in his Islington North constituency.

The Brotherhood has been accused of engaging in terrorist activities and is proscribed across much of the Middle East and in Russia.

A counter-extremism activist compared Mr Corbyn’s behaviour to a right-wing politician showing support for the BNP.

It came as Mr Corbyn refused to apologise for attending a highly controversial commemoration at a Palestinian graveyard where he was accused of laying a wreath at the graves of four men alleged to have been behind the Munich Olympics massacre.

He also gave yet another muddled explanation of what he was doing there, in which he appeared to accept for the first time that he had been honouring members of Black September, as well as others.
