Far-right group English Defence League (EDL) will protest outside Parliament today.
The EDL originally planned to demonstrate in Walthamstow, but the MET Police banned all marches there for 30 days.
EDL says it's a movement opposed to Islamic extremism, but critics say it's racist.
Waltham Forest Councillor Chris Robbins says the ban "is a victory for the ordinary residents."
But EDL has told the police it will try to stage more protests there once the ban is lifted.
