A senior member of the SDLP has hinted his party may consider its position on the Policing Board and District Policing Partnerships if a Parades Commission ruling in north Belfast is not enforced this evening.
The Parades Commission has told the Ballysillan and Ligoniel Orange lodges they cannot be accompanied by bands, or by its supporters, as they make their return parade this evening past the flashpoint shops in the nationalist Ardoyne area.
A "feeder" parade passed the area peacefully this morning.
DUP North Belfast MLA Mr Nelson McCausland, a member of the Orange Order, said he believed the police would allow the supporters to walk back. "At the end of the day people have to get home. There is no other road back to Ballysillan. This road is their umbilical cord to the city centre."
But former Belfast Lord Mayor Martin Morgan said the police must not defy the ruling by allowing supporters through on the return leg.
"If policing is seen to be negative, is seen to be going back a number of years, the SDLP has to deliver a very clear message to the Secretary of State and to the British government.
"If you want our participation in these bodies, then let's see policing work in this area."
