A series of marches by a right-wing group has been banned amid fears of violence on the streets.
Policing minister Damian Green agreed to the Metropolitan Police request for the ban, in a bid to stop serious public disorder ahead of marches by the English Defence League in Waltham Forest, Tower Hamlets, Newham and Islington.
"Having carefully considered the legal tests and balanced rights to protest against the need to ensure communities and property are protected, I have given my consent to a ban on all marches in Waltham Forest and three nearby boroughs for a 30-day period," Mr Green said.
"I know the Metropolitan Police are committed to using their powers to ensure communities and properties are protected."
The Metropolitan Police wrote to Home Secretary Theresa May asking for the ban two days ago.
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."
