A controversial Easter commemoration parade which sparked violent scenes last year is due to take place in Derry next Monday.
The annual event is being organised by the Derry 1916 Commemoration Committee, which has the support of anti-agreement party Saoradh.
It is understood posters advertising this year’s parade were put up in Derry at the weekend.
A similar parade held on the 25th anniversary of the Good Friday Agreement, which fell on Easter Monday last year, ended in outbreaks of violence.
Petrol bombs and other missiles were thrown at PSNI vehicles as the unnotified parade, led by a masked colour party, made its way through the Creggan area to the city cemetery for a short commemoration.
Several people are currently facing charges in connection with the commemoration event.
Violence also broke out in 2022 when the PSNI moved in to arrest suspected members of a colour party after a similar parade arranged by the National Republican Commemoration Committee.
Petrol bombs and other objects were thrown at PSNI vehicles at an entrance to the city cemetery.
In 2018 petrol bombs and other missiles were thrown at the PSNI after trouble flared at a similar unnotified Easter parade.
Traditionally, the organisers of the Derry parade do not notify the Parades Commission of their intention to march despite a legal requirement to do so.
It is understood, that as on previous occasion, this year’s event will also not be notified.
SDLP MLA and Policing Board member Mark H Durkan said: “I would be urging the organisers to go down the lawful route.
“There’s a process there for events of this nature and I would ask them to abide by it.
“They know what will happen as a consequence of not doing it and one can only conclude that’s what they want to happen, if they are not abiding by the law.”
Mr Durkan said his party has also spoken to the PSNI “about the need to be sensible and sensitive in their approach to these issues as well”.
