The jury in Jeffrey Donaldson's trial for historical sex offences began deliberations on 17 June 2026, after the judge summed up the case. Donaldson, who led the Democratic Unionist Party (DUP) from 2021 until his resignation in March 2024, faces 18 charges in total, including one count of rape. He entered a not guilty plea to all 18 counts at Belfast Crown Court on 10 September 2024, per Reuters. The charges relate to alleged conduct that took place years before he became party leader.

The judge summed up proceedings on 18 June 2026, according to reporting from Yahoo News, and the jury has now begun consideration of the evidence. No timeline for a verdict has been publicly indicated.

For Northern Ireland, this trial carries exceptional political weight. Donaldson spent over two decades as one of the most senior figures in unionism. He was a Westminster MP for Lagan Valley, took part in the negotiations that implemented the Good Friday Agreement (the 1998 peace settlement), and played a central role in the DUP's long negotiations with UK governments over the Windsor Framework—the post-Brexit trading arrangements that govern Northern Ireland's place in the UK's trading system. His arrest and resignation from the DUP leadership in March 2024, announced on the same day as the charges became public, were without recent precedent in the party's history.

The DUP moved quickly to appoint Gavin Robinson as interim leader, before settling on a longer-term arrangement. The timing proved difficult: Stormont—the Northern Ireland Assembly—had only recently returned to work after a two-year DUP boycott over post-Brexit trading issues. For a party already split over the Windsor Framework, the loss of Donaldson's leadership added significant instability at a moment when the institution was already fragile.

Criminal proceedings in Northern Ireland follow the same broad legal framework as the rest of the UK, though the jurisdiction has its own court structure and prosecutorial arrangements through the Public Prosecution Service for Northern Ireland. The case is being heard before a jury, and the presumption of innocence applies in full—the charges have not yet been tested to a verdict.

With 18 counts spanning years of alleged conduct, jury deliberations are unlikely to be quick. Juries in complex multi-count cases are routinely directed to consider each charge separately, a process that typically extends over several days. The judge's summation would have explained to jurors the legal test for each count: the standard of proof beyond reasonable doubt.

The broader political context here matters beyond the immediate legal outcome. Donaldson's career touched some of the most sensitive moments in the recent history of the UK: the St Andrews Agreement, the Stormont House Agreement, and the DUP's confidence-and-supply deal with Theresa May's government from 2017 to 2019. None of that institutional history is on trial. The charges concern personal conduct. Yet the verdict will likely prompt scrutiny of the period during which the allegations are said to have taken place and the structures—party and parliamentary—within which he operated.

The DUP, now working to stabilise its position ahead of any future Assembly or Westminster election, will be watching closely. A verdict closes one chapter. What happens next—for the party, for unionism, and for Northern Ireland's still-fragile political settlement—is a separate question.
