Lara Bird, the Scottish National Party candidate, holds an overwhelming lead in trader consensus for the 18 June 2026 by-election in the Arbroath and Broughty Ferry constituency, reflecting the party's recent hold on the seat and limited time for challengers to build support ahead of polling. The vacancy arose after the prior SNP MP transitioned to the Scottish Parliament, prompting a short campaign in a first-past-the-post contest where local party machinery and voter familiarity typically favor continuity. Other named candidates, including Liberal Democrat Tanvir Ahmad and independents or minor-party figures such as Bill Reid, register far lower implied probabilities due to weaker organizational backing and the absence of major national swings or scandals altering the baseline. Multiple unidentified entrants at 50% highlight residual uncertainty over turnout or late shifts, yet historical patterns in similar Scottish by-elections underscore the structural advantage for the defending party.
