The Democratic Unionist Party's 2024 manifesto was built on three demands: full restoration of Northern Ireland's place within the United Kingdom, removal of the Irish Sea border the Windsor Framework had left in operation, and defence of cross community consent as the foundation of Stormont devolution. The election delivered five seats, three down from eight in 2019, the party's lowest Westminster representation since 2001. North Antrim fell to TUV leader Jim Allister by 450 votes, ending the 54 year Paisley dynasty that had held the seat since 1970. Lagan Valley, held by two former unionist leaders, fell to Alliance's Sorcha Eastwood. South Antrim was lost to the UUP's Robin Swann by 7,512 votes. Of the five seats the DUP held, Gregory Campbell survived in East Londonderry by 179 votes and Sammy Wilson held East Antrim by 1,306. Gavin Robinson, who had succeeded Jeffrey Donaldson as leader after Donaldson's arrest on historic sexual offence charges in March 2024, held Belfast East with a slightly increased majority. Sinn Féin finished ahead of the DUP in seats and votes for the first time, becoming the largest Northern Ireland party at every level of elected government: Westminster, the Assembly, the European Parliament and local councils. The DUP is no longer the largest unionist party at Westminster. It entered this Parliament diminished, divided and led by its fourth leader in three years.

On the constitutional union the manifesto's defining commitment was that the Irish Sea border be ended and EU law removed from Northern Ireland. The January 2024 Safeguarding the Union Command Paper restored Stormont after a two year boycott but did not remove the Windsor Framework or the Sea border. Robinson, who had initially supported the deal, later said "cautious realism" should have been the response. Four of the DUP's eight Westminster MPs at the time considered the deal oversold and did not hide their scepticism. The Sea border remains in full operation. Labour's UK Government has shown no willingness to reopen the framework. The constitutional arrangement the DUP demanded be reversed is the constitutional arrangement the DUP now operates within. Stormont has been down for nearly 40 percent of the post Good Friday Agreement era. The DUP collapsed it twice. The second time lasted two years. The deal that ended the boycott delivered less than the boycott demanded.

On Stormont, the DUP's Emma Little-Pengelly serves as deputy First Minister under Sinn Féin's Michelle O'Neill as First Minister. The party that spent decades opposing power sharing with Sinn Féin now holds the junior role in a Sinn Féin led Executive. Robinson has warned against reform proposals that would dilute cross community consent and replace the designation system with weighted majority voting. Alliance has called for exactly that, arguing the current system enshrines sectarian division. The DUP's structural defence of cross community consent is also a defence of the mechanism that gives unionism a veto it would lose under any alternative arrangement.

On the economy the manifesto committed to lower Northern Ireland corporation tax. The ask requires Westminster legislation. The DUP's leverage at Westminster contracted from confidence and supply under Theresa May (2017 to 2019), when its 10 MPs extracted over £1 billion in additional funding for Northern Ireland, to the backbench role of a five MP group with no bargaining power. At five MPs in a 650 seat parliament, the DUP cannot force Westminster engagement on anything. The corporation tax ask remains in abeyance.

On welfare the manifesto opposed the two child benefit cap as it applied in Northern Ireland. Labour scrapped the cap at the November 2025 Budget. The headline welfare ask has been delivered by the UK Government rather than achieved through DUP advocacy. The party can claim alignment with the outcome. It cannot claim credit for it.

The Donaldson conviction on 22 June 2026, guilty on 18 counts of sexual offences including rape against victims who were children at the time of the abuse, is the most severe criminal disgrace to befall any party leader in the history of Northern Ireland politics. Robinson called Donaldson's behaviour "predatory and repugnant" and demanded he be stripped of his knighthood. The party that Donaldson led into the Safeguarding the Union deal must now answer for how long his behaviour was unknown, what internal processes existed and whether any warnings were missed. That reckoning has not yet begun.

The DUP's 2024 manifesto demanded a constitutional settlement Westminster has not been willing to provide and will not provide. The party operates inside institutions it argued were structurally compromised. The Sea border remains. Cross community consent is under reform pressure. The DUP criticises both. The DUP has no leverage to change either. On its first election night under Robinson's leadership the party lost three seats, nearly lost two more, ceded its status as the largest Northern Ireland party at Westminster, watched the 54 year Paisley dynasty end by 450 votes, and entered a Parliament where its former leader would later be convicted of raping children. What remains is a party frozen between a constitutional position it cannot achieve and an institutional role it cannot abandon, led by a man who inherited a crisis not of his making and has not yet been given the political space to define what the DUP stands for beyond opposition to arrangements it has already accepted.
