Alloa and Grangemouth.

Leishman has been one of Labour's more restive backbenchers, and his most striking recent move was voting to refer Prime Minister Starmer to the Privileges Committee over the Mandelson appointment -- breaking with his party on an issue of direct accountability for the leadership. That sits alongside five rebel votes since entering Parliament, including opposing tuition fee rises, Public Order Act protest regulations, and welfare cuts. On the last of those, his deviations from Labour's position are the sharpest in the data: he votes with disability and welfare protection stances at rates between 50 and 88 percentage points above his party average, a consistent pattern rather than a one-off gesture. Locally, his campaign against the Grangemouth closure drew significant coverage, and he said publicly in January that Labour had "hurt" him -- but that the answer was more left-wing voices inside the party, not outside it.

His parliamentary participation sits at 74%, a little below the Commons average, with 191 contributions across 146 debates since 2024. He is a 94.6% party-line voter overall, meaning most of his voting record is orthodox Labour -- but his deviations cluster tightly around welfare, civil liberties, and public order, where he leans consistently left of the whip. Speeches concentrate on economy and jobs, social care, energy, and cost of living, reflecting both ideological priorities and the industrial character of Alloa and Grangemouth.

His constituency work has generated largely positive local coverage -- tabling an Early Day Motion on STV news centralisation, raising pension failures among civil servants, and pushing back on college funding cuts. He holds no committee seats. News sentiment across the past 90 days averages a moderate 0.45, with mp-performance coverage (four articles) running notably cooler than culture and community pieces.
