Voters are casting ballots in two Scottish by-elections, covering Aberdeen South and Arbroath and Broughty Ferry. Polling closes across both constituencies in the evening, with results expected to be announced in the early hours of Friday. The elections follow the scheduled by-election timetable for each seat, and the outcome will determine who wins the parliamentary representation for the constituencies. Reporting indicates that the vote count is set to begin after polling ends, and the official results are due shortly thereafter. While specific details on campaigning, turnout, or candidate line-ups are not included in the provided excerpts, all sources note the same key timeline: polling closes in both constituencies and the results are expected overnight into Friday morning. The final figures will reveal the winning candidates and the level of support each contest receives, based on votes cast during the by-election period.
