Up to 1,000 loyalist protesters are expected to march through Dublin city centre tomorrow to a rally at Leinster House.
Afterwards a delegation from the march led by the DUP's Jeffrey Donaldson will meet the Minister for Justice, Michael McDowell.
The parade will be led by six loyalist bands, with Orangemen and unionist politicians taking part. The march is taking place to commemorate those who died in republican violence during the Troubles.
The protest march will begin at 12.30pm at Parnell Square North and will follow a route from Cavendish row, O’Connell Street, making its way to Molesworth Street.
The rally is due to be addressed by Jeffrey Donaldson at Leinster House.
The Orange Order is backing the march but has advised its members who take part not to wear orange regalia. The order wants the focus of the parade to be fixed on the victims groups taking part.
Motorists are advised that parking restrictions will be in place around Merrion Square.
