Home Secretary Theresa May has authorised a ban on a proposed march by the English Defence League (EDL) in Leicester.
The right-wing group said it expected 3,000 members to attend a rally in the city on 9 October.
Concerns about the march and a counter-demonstration by Unite Against Fascism (UAF) were raised by Leicestershire Police's chief constable.
The blanket ban prevents any group marching in the city on that date.
However, it does not prohibit static protests by the EDL and UAF, such as those that took place in Bradford in August after a similar ban on proposed marches.
A spokesman for the Home Office said: "Having carefully balanced rights to protest against the need to ensure local communities and property are protected, the Home Secretary gave her consent to a Leicester City Council Order banning any marches in the city on October 9.
"Leicestershire Constabulary are committed to using their powers to ensure communities and properties are protected and we encourage all local people to work with the police to ensure community cohesion is not undermined by public disorder."
Leicester City Council applied for the ban at the request of the police after formal notification was received that both the EDL and UAF intended to march.
Sheila Lock, the council's chief executive, said: "Even though the Home Secretary has given her consent it does not prevent any static protests taking place, which are still lawful provided they remain peaceful, as we, nor the police, have legal powers to prevent them.
"There are lots of activities being planned during the coming week to celebrate Leicester and I'd encourage people to join in."
