In particular the demonstration was to show support for Burmese student leaders imprisoned for 65 years by the Burmese military dictatorship, and to urge the UK Government and UN Secretary-General Ban Ki-moon to take urgent action.

Those taking part wore white clothing, both because this is the prison uniform in Burma and also because white represents police.

While I was taking pictures there was heavy traffic past the demonstrators and their banners, and a number of motorists sounded their horns to express support for the cause.
