When the
Northern Ireland Assembly and
Executive were established in 1998 and 1999 respectively, all eligible parties were required to nominate ministers to serve on the Executive. No provision for an Official Opposition or for the role of Leader of the Opposition was made. Non-Executive parties continued to fulfil the role of an opposition in an unofficial capacity, much as various Nationalist and Labour MPs had done in the
House of Commons. The '''''' (c. 10 (N.I.)) established provisions which allowed for a creation of an Official Opposition, with certain rights and entitlements associated with the role. Assembly standing orders subsequently made provision for the creation of a “Leader of the Opposition” and “Deputy Leader of the Opposition”, to be nominated by the largest and second-largest parties which are entitled to membership of the Official Opposition. After the 2016 election the
UUP and
SDLP decided to form the Official Opposition. However, neither party opted to nominate individuals to the roles of Leader and Deputy Leader. Following the SDLP declining to nominate an Infrastructure Minister to the Executive, on the 25 July 2022 the SDLP formed an opposition and nominated
Matthew O’Toole as the first Leader of the Opposition in the Northern Ireland Assembly. == List of Leaders of the Opposition ==
