Guantanamo protesters press Blair

The march began in Parliament Square

A chain-gang in Guantanamo-style boiler suits marched on Downing Street to call for the release of UK citizens held at the US detention camp.

The protesters were joined by relatives of eight men still held without charge in Camp Delta.

Family members handed in a letter for Prime Minister Tony Blair, saying he is key to the men's release.

The Amnesty International protest called on the government to intervene to secure the men's return home.
