A planned march by the English Defence League through Walthamstow this weekend has been banned by the Home Secretary.
The ban prevents all marches in Waltham Forest, Islington, Tower Hamlets and Newham for 30 days.
Protesters will be allowed to gather outside the Houses of Parliament for an hour.
Police say they were concerned there would be serious disorder if the march went ahead.
Chief Superintendent Peter Terry said: "We have made this decision based on specific intelligence and information, and our message is clear, we do not want people coming into the areas to attend these events."
