A major security operation is being launched in Nottingham to stop violence flaring up during a demonstration by the English Defence League (EDL).
To add to the police's workload, Unite Against Fascism is planning a counter-protest at the same time, while the Mercian Regiment is holding a homecoming parade through the city hours earlier.
Meanwhile, Nottingham Forest FC play local rivals Leicester City at home just as the demonstrations will be held a few hundred yards from the city's main shopping area.
Nottinghamshire Police said scores of officers were being drafted in to prevent violence during the protest by the EDL, a relatively new group which says it stands against the spread of Islamic extremism.
The 2pm protest outside Nottingham Castle will follow a homecoming parade by the Mercian Regiment at 10.50am, while Forest kick off their match against Leicester at the City Ground at 1pm.
