A march has traditionally taken place in Derry each year to mark the anniversary of Bloody Sunday Thousands of people are due to join what is intended to be the last Bloody Sunday march in Londonderry.
Organisers said they believe the annual event should come to an end following the publication of the Saville Report.
A statement, signed by the majority of the victims’ families, said the protest was no longer necessary after the inquiry exonerated those who died in the 1972 Bloody Sunday shootings.
But some relatives of the victims have called the proposal premature.
Demonstrators will walk from Creggan to Guildhall Square at 1430 GMT.
Fourteen people lost their lives on 30 January 1972 when British paratroopers opened fire on a civil rights march in Derry’s Bogside area.
Kate Nash, whose brother William was killed on Bloody Sunday, said she felt the decision to end the march was “very premature”.
She added: “It was dropped on us like a ton of bricks, completely unexpectedly. Who decided the march should end and why?
“The people of Derry were not afforded the opportunity of having an opinion about this and I feel they should have had.”
Tony Doherty, whose father Paddy was also killed on Bloody Sunday, said he supported the ending of the march.
He added: “The vast majority of the families felt that what we had brought about, what we had achieved on 15 June, with the Saville Report as an exoneration, with the words of David Cameron, with apology and accepting political responsibility for the atrocity of Bloody Sunday, that it was now time for us all to consider moving on.”
A number of options are now being considered to mark future anniversaries, including an annual gathering of remembrance at the Bloody Sunday monument, a remembrance Mass, a human rights weekend and an annual Bloody Sunday lecture.
