The right-wing English Defence League (EDL) is to hold a march in Cambridge for the first time.
Cambridgeshire police has confirmed it has been approached by the organisation to hold a demonstration on Saturday, July 9.
A counter-demonstration will be held on the day organised by the Cambridge branch of Unite Against Fascism, which will meet in market square at 11am.
Martin Booth, spokesman for Unison at Cambridge health branch, said: “We have a lot of diversity at Addenbrooke’s and in Cambridge and we don’t want these characters coming to the city.”
An EDL march in Peterborough last year was policed by about 1,000 officers from 18 forces.
A police spokeswoman said: “We have been approached by a member of the English Defence League to inform us of a protest in Cambridge on July 9.
“Plans are underway to ensure an appropriate police response on the day.
“The force fully supports people's right to peaceful protest, as well as ensuring minimal disruption to the people of Cambridge.”
Trade unionists, politicians, faith group and community leaders have already signed up to a statement opposing the EDL and supporting the multi-cultural “We are Cambridge” event.
