The graph below shows the latest What Scotland Thinks/ScotCen Poll of Polls of voting intentions in Scotland for the 2015 UK general election and how it has evolved over time.
The latest Poll of Polls is based on two polls by Survation, one by YouGov, and one by TNS BMRB. Between them the four polls were conducted between 30 January and 17 March. The most recent addition is a poll by Survation whose fieldwork was concluded on 17 March. (At the same time the series now also includes an earlier Survation poll whose fieldwork concluded on 10 March, but whose results were not published until 19 March.)
In the 2010 general election, Labour won 42% of the vote in Scotland, the SNP 20%, the Liberal Democrats 19%, the Conservatives 17%, UKIP 1% and the Greens 1%. If the difference between those figures and the parties’ ratings in our latest poll of polls were to be replicated in each and every constituency, the Conservatives would win 1 seat, Labour 10, the Liberal Democrats 1, the SNP 47, UKIP none, and the Greens none.
