Devolution returned to Northern Ireland on 8 May 2007.
The then British Prime Minister Tony Blair and Irish Prime Minister Bertie Ahern were at the Northern Ireland Assembly's headquarters at Stormont in Belfast for the occasion.
Direct rule by London ministers ended at midnight, bringing back power-sharing to Northern Ireland after a five-year break.
Ministers from the four main political parties took a pledge of office.
The Assembly's First Minister is Peter Robinson of the DUP.
The deputy is Martin McGuinness of Sinn Fein.
