Tapp's most distinctive recent act was backing the assisted dying bill at Report Stage in June 2025, voting for two new clauses on guidance and regulatory consultation that his party majority opposed — one of only three rebel votes in his parliamentary career so far. The other came in December 2024, when he voted against a Lib Dem motion to introduce proportional representation, also against the Labour majority. Beyond those two moments, he has voted with his party on virtually everything: nationalising the railways, the Steel Industry (Nationalisation) Bill, and clean air zone fee reforms all carried his vote in June 2026.
At 77% voting participation — slightly below the Commons average — and 99.3% party alignment, Tapp is a broadly loyal, moderately engaged backbencher. His 205 contributions across 73 debates lean heavily on immigration (45 speeches) and crime (25), both topics with direct local relevance to a constituency that includes the Port of Dover. He is notably more aligned with local government powers than his party average (+26 percentage points), and more sympathetic to criminal justice reform. He has no committee roles, which limits his formal influence over legislation.
The clearest picture of Tapp outside the chamber is in his constituency work. He drew attention in early 2026 for publicly condemning an antisemitic art exhibition as "completely unacceptable," and has run a sustained "Tapp into Politics" initiative engaging school pupils with democracy — covered positively in local press. His personal military background, which he has cited in defence debates, adds context to his advocacy for veteran housing in Dover. News coverage over the past 90 days is broadly neutral, with 26 articles averaging a marginally positive sentiment score of 0.14.
