Nesbitt, a former UUP leader, had held the high-pressure health portfolio in the Northern Ireland Assembly since May 2024.
The Clash Over Causeway Hospital Emergency Surgery
The immediate catalyst for the resignation centers on contrasting approaches to regional health reform. Last week, UUP leader Jon Burrows attended a heated town hall meeting in North Antrim where he publicly opposed the removal of emergency general surgery (EGS) from Causeway Hospital. Burrows told constituents that emergency surgery must remain at the facility and be built up rather than run down, declaring that his position was not for negotiation.

Mike Nesbitt missed that specific town hall due to a constituency election meeting in Strangford, leaving his party leader to take the floor. While Burrows argued that reform must be made with communities rather than simply imposed on them, the Department of Health was still awaiting a final clinical recommendation to land on the minister’s desk. Burrows later acknowledged that how reform is delivered matters just as much as the final decision, noting that the strong public reaction in Causeway showed the risks of communities feeling sidelined.
But there is a catch. The Northern Health Trust had previously recommended consolidating emergency general surgery onto a single site. This placed Nesbitt in the difficult position of balancing clinical evidence and long-term modernization against immediate local political opposition.
Legacy and Political Fallout Within the Ulster Unionist Party
A UUP spokesperson confirmed that Nesbitt chose to step down from the health portfolio, offering sincere thanks for his service and leadership under immense pressure. According to the party, Nesbitt tackled one of the most demanding briefs in government with a genuine determination to improve health and social care across Northern Ireland.

During his tenure, Nesbitt initiated a shift toward a neighbourhood model of care, placed health inequalities at the center of policy, and targeted Northern Ireland’s notoriously long waiting lists. Before taking the health brief, Nesbitt served two separate stints as UUP leader from 2013 to 2017 and again from 2024 until earlier this year when Burrows assumed the party leadership. First elected as a Strangford MLA in 2011 following a prominent broadcasting career, Nesbitt also previously served as Northern Ireland’s commissioner for victims and survivors.
