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 YouGov, one poll by Panelbase, and one by TNS BMRB. Between them the four polls were conducted between 1 and 23 April. The most recent addition is a poll by TNS BMRB whose fieldwork was concluded on 19 April but whose results were not published until 27 April, after two polls that had a later fieldwork end date. This is thus a revised version of the previous poll of polls dated 23 April.
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, Labour would win 3 seats, the Liberal Democrats 1, the SNP 55, the Conservatives none, UKIP none, and the Greens none.
