Robinson's most distinctive recent move was a lone rebel vote against his own party on a Mental Health Bill clause in October 2025 — the only occasion in the current data where he broke from DUP ranks, in an otherwise near-total 99.7% party-line record. Recent votes show him consistently opposing Labour government measures: he voted against machinery safety regulations that extend EU rules to Northern Ireland under the Windsor Framework, arguing they deepen a democratic deficit, and against planning delegation rules he sees as eroding local accountability. He drew criticism in March 2026 when a Belfast columnist attacked his decision to host Robert Jenrick, questioning his judgment on who he aligns the DUP with. Separately, he condemned the band Kneecap in Stormont as a "hatefest" promoting division, and called a Lurgan bomb attack a return to Troubles-era proxy violence.
At Westminster, Robinson votes at 57% — below the Commons average — though Northern Ireland MPs routinely miss votes on England-only legislation, which partly explains the figure. He scores strongly on parliamentary scrutiny (89%), Lords scrutiny (100%), crime (93%) and armed forces welfare (79%), and weakly on climate action (16%), progressive taxation (0%) and workers' rights (14%). His speeches concentrate on economy and jobs, defence, and crime across 159 contributions in 89 debates, suggesting a broad brief rather than a narrow specialism.
Robinson sits on the Northern Ireland Affairs Committee, which frames his consistent focus on the Windsor Framework and Northern Ireland's constitutional position within the UK. He led a parliamentary debate on victims of terrorism in March 2025, reflecting a long-standing DUP concern. News sentiment data for the most recent 90 days is insufficient to establish a current trend, and the rebel vote data covers only one instance, limiting conclusions about how far he might diverge from party leadership under pressure.
