The organisers of a controversial pro-Palestinian march through central London of Sunday have told protesters that they can wave Hezbollah flags.

In a statement on the website of the Islamic Human Rights Commission, participants were told that they “are welcome to bring flags that show solidarity with the Palestinian cause” but flags of proscribed or illegal organisations are not allowed.

However the group said: “You can bring a Hezbollah flag to show support for the political wing of Hezbollah. This is because the political wing of Hezbollah is not a proscribed organisation.”

Hezbollah is a Lebanon-based militia with tens of thousands of rockets trained on northern Israel, and Jewish representatives have long argued that the group itself makes no distinction between its political wing and its armed wing.

London Mayor Sadiq Khan is due to discuss the march with Metropolitan Police Commissioner Cressida Dick tomorrow, after more than 8,000 people signed an online petition calling for the annual march to be banned.
