Nothing should be done to help unionists undermine the Parades Commission, Derry Sinn Fein MLA Raymond McCartney.
Orange men have been banned from marching through the centre of Strabane and through the nationalist Ardoyne area of Belfast.
Mr McCartney was speaking after the Orange Order announced plans for protests and called for a Commission of Inquiry into the parade through Ardoyne.
He said: “The Parades Commission was set up and constituted by statute as an independent body to deal with disputed parades.
“Unionists are asking for a Commission of Inquiry simply because they didn’t get their own way.
“Neither unionists or the British Secretary of State should do anything to undermine the Parades Commission.
“The myth of the hollowing out of British culture flies in the face of the facts.
“The number of parades has doubled in the last five years, the number of loyalist bands has also doubled and more than 95 per cent of all loyalist parades are uncontested.”
Mr McCartney concluded: “Walking out of talks with their partners in government and demanding that the British Secretary of State imposes a unionist solution can only raise tension and inflame the situation.”
