Clapham Common is to host Europe's largest anti-racist festival.

Rise: London United 2007, backed by London's Mayor Ken Livingstone, is to take place on the common on July 15.

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

The festival, initially named Respect, 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, fair ground, 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 Rise: London United is taking place in Clapham, which has strong historical links to the campaigners who helped bring in the legislation, which brought to an end the transatlantic slave trade in Britain,' he said.

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