Scotland Yard say a march in central London this weekend could be the biggest demo in the city since a million people protested against the Iraq war in 2003.
A hundred thousand people are expected to turn out for a demo in Hyde Park against the Government's spending cuts.
Police say they're prepared for any violence, with 4,500 officers on duty.
Troublemakers are being warned to stay away.
