An annual anti-racist festival will no longer take place on Clapham Common as it is not large enough.

Rise: London United was scheduled to take place on the common on July 15 but London Mayor Ken Livingstone decided to move the free music festival to Finsbury Park rather then reduce the size of the event.

Lambeth Council says it backs the mayor's decision to move the festival to Finsbury Park.

Mr Livingstone said he invited people "across London to come Finsbury Park on 15 July, to reinforce the message that all Londoners stand together and will not accept racism in the most diverse city in the world."

The free music festival was originally organised by the Trades Union Congress and is still supported by the union.

Initially named Respect, the festival was revived by Mr Livingstone in 2001 and attracted around 60,000 visitors. Numbers have more recently reached around 100,000.

Last year's event, held at Finsbury Park on July 8, saw artists including Graham Coxon Sway, the Buzzcocks, Killa Kela and The Wailers. The event also had a children's play area, fairground, exhibitions and arts and crafts.

The mayor said the venue for this year's event had extra significance in 2007 - the bicentenary year of the abolition of the Transatlantic slave trade.

This year's line-up has not yet been announced.
