Sixty extra police officers have been drafted in to help keep Rotherham safe on Saturday when two demonstrations are held in the town at the same time.
The English Defence League is planning another protest following the publication of a report into child sexual exploitation, which revealed 1,400 children were abused over a 16 year period while the authorities turned a blind eye.
The report suggested police and council chiefs ignored the issue because of cultural sensitivities around the ethnicity of offenders - largely Pakistani men.
At the same time as the EDL demo on Main Street, between 1.45pm and 2.45pm, Unite Against Fascism will hold a counter protest on the same street.
A South Yorkshire Police spokeswoman said: “It is anticipated that up to 100 members of the EDL will protest on Main Street between 1.45pm and 2.45pm, with United Against Fascism expecting to hold a counter protest on a different part of Main Street at a similar time.
“Rotherham town centre will be open as usual and there are no planned road closures.
Sixty, additional South Yorkshire Police officers will be on duty to ensure a peaceful protest and to keep people and property safe.
“Police expect everyone involved in the event to behave appropriately and respect the right of other people to go about their daily lives with a minimum of disruption.”
