Voters in Scotland remain evenly split over supporting independence from the rest of Britain, a poll published by the Sunday Times showed, days after the Scottish government set out plans for a referendum on the subject next year.

Last week, Scotland’s first minister Nicola Sturgeon announced plans for a second independence referendum to be held in October 2023 and vowed to take legal action if the British government blocks it.

The Panelbase survey showed 48% of respondents were in favor of independence, 47% were opposed and 5% did not know. A previous online Panelbase poll in April had 47% in favor and 49% against.

The latest results were based on a sample size of 1,010 people.

British Prime Minister Boris Johnson and his ruling Conservative Party strongly oppose a referendum, saying the issue was settled in 2014 when Scots voted against independence by 55% to 45%.

Other polls in 2022 vary, with some showing a similar split to the 2014 result, and others showing the gap narrowing.
