The BBC has confirmed that it will not be appealing Gerry Adams' libel case victory.
The former Sinn Féin leader sued the corporation over a 2016 BBC Northern Ireland Spotlight story and online article on the murder of British agent Denis Donaldson.
Last month, a jury found Mr Adams, 76, was defamed when it was alleged by an anonymous contributor that he sanctioned the 2006 killing and awarded him €100,000 (£84,000) in damages.
The combined legal costs of both parties is estimated at between €3-5m (£2.5-4.2m), according to sources with knowledge of the case.
A BBC spokesperson said: "We have given careful consideration to the jury's decision.
"We will not be appealing its verdict, bringing this matter to a conclusion. We remain committed to public interest journalism and to serving all BBC audiences."
