Some of the families of those killed on Bloody Sunday have expressed concern at another delay to the Saville Inquiry's report on the shootings.
13 people died after British paratroopers opened fire during a civil rights march in Derry in January 1972. A 14th victim died later from injuries.
Tribunal chairman Lord Saville said he was 'extremely disappointed' that the report would not be given to the British government until 22 March next year.
The Bloody Sunday Trust's Eamonn McCann said this would be bad timing as it was possible that the report would be published in the middle of a Westminster election campaign.
SDLP leader Mark Durkan said the delay would have severe implications and could create many complications.
The Northern Secretary, Shaun Woodward, said he was 'profoundly shocked' by the delay.
He said he was concerned at the impact on the families of those who lost loved ones and those who were injured and was equally concerned at the increased anxiety that soldiers serving on the day would suffer.
It is expected the British government will take some time to consider Lord Saville's findings before publishing them.
In a letter to legal teams, Lord Saville said the report, which will run into thousands of pages, must be with publishers for some months before it can be finalised.
The Bloody Sunday Inquiry is the longest and most expensive inquiry in British legal history.
The first witness testimony was heard in November 2000 and the last in January 2005.
The tribunal received 2,500 statements from witnesses, with nearly 1,000 of these called to give direct evidence.
