Crowds are expected to gather on Tottenham Green tomorrow to cheer on the People's March for the NHS.
The march, which began in Jarrow on August 16, is expected to proceed from Edmonton Green down Tottenham High Road at around 10.30am. It will then make its way to central London.
Marchers are protesting against the government's health policies.
Haringey TUC secretary Keith Flett said his union would be supporting the march.
He said: "There is real concern about what the policies of the present government are doing to our health service and the march is an excellent way of drawing attention to this."
