Reform UK recorded a strong performance in England's local elections. Some unionists in Northern Ireland welcomed the result. Others expressed caution over Reform UK's focus on English concerns.

Unionists noted that movements based outside Northern Ireland may overlook local constitutional complexities. Brexit experiences left many feeling isolated after the Northern Ireland Protocol took effect under Boris Johnson's government.

Matthew O’Toole MLA, leader of the opposition in the Northern Ireland Assembly, called for preparation against potential changes from English, Scottish, and Welsh politics. He highlighted Reform UK's positions, including plans to reopen the EU-UK agreement on the Irish Border.

O’Toole pointed to Reform UK's Brexit spokesperson Danny Kruger addressing a Traditional Unionist Voice conference on completing Brexit business. The party advocates protecting British veterans from accountability for Troubles killings.

Sinn Féin holds the largest number of seats in the Northern Ireland Assembly. Nationalist parties lead devolved administrations in Scotland and Wales.

O’Toole argued that citizens in Northern Ireland, including some from unionist backgrounds, may reject a UK government led by Reform UK. He referenced the Shared Island Fund as an alternative to Stormont challenges and noted Irish passport applications among constituents.

Brexit has reduced UK economic activity by at least £100 billion yearly, increasing public service pressures north of the border.
