The Bloody Sunday families are divided over whether today's march to mark the 39th anniversary of those murdered by British paratroopers will be the last, with some relatives pledging to continue to organise the annual event. Thousands are expected at today's gathering in Derry, which will retrace the route taken by the original civil rights protestors in 1972. Demonstrators will march to the Guildhall for a rally which will be addressed by Sinn Féin president Gerry Adams, SDLP MP Mark Durkan, and Gerry Duddy, whose brother Jackie was killed.

Last year, the Saville report cleared the names of the 14 people murdered and British prime minister David Cameron apologised for the shooting.

Most families believe it's now no longer necessary to continue the annual march. However, some relatives strongly disagree.

John Kelly, whose brother Michael (17) was among the dead, said: "Our campaign has achieved its goals. We have highlighted the lies and injustice carried out by the British Army and government... We will continue to commemorate Bloody Sunday... but it's time to end the march."

However, Liam Wray, whose brother Jim (22) was also murdered said: "For as long as there's breath in my body, I hope that I will be marching to remember those killed on Bloody Sunday.

"It doesn't matter whether there are 10 or 10,000 marchers in future; it's the principle."
