Unionist parties have joined an Orange lodge in hitting out at a Parades Commission ruling which has barred a march from passing a North Belfast interface.
Ballysillan lodge's proposed parade on Saturday was a "clear breach" of a 2016 agreement with a local residents' group, the parades body said.
The lodge planned to march along Crumlin Road past the mainly nationalist Ardoyne area and Twaddell Avenue, where parading disputes have previously sparked serious disorder.
