Dissident Republican Colm Murphy has been found guilty of plotting to cause the Omagh bombing.

Panorama: Who Bombed Omagh? examined evidence relating to Mr Murphy's mobile phone calls. This evidence is now described as being at the heart of the case against him.

Former Northern Ireland Secretary Peter Mandelson praised the programme as "well-researched and authoritative" in a letter to the Telegraph newspaper on 23 January.

While welcoming Mr Murphy's conviction, Mr Mandelson also pointed out that Panorama identified three other possible suspects and called for people to co-operate with the police.

The blast - later admitted by the dissident republican Real IRA - killed 29 people, including a woman pregnant with twins, and injured hundreds.

The father-of-four was the only person charged in connection with the bombing on 15 August 1998.
