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 one poll by Survation, one poll by YouGov, one poll by Panelbase, and one by Ipsos MORI . Between them the four polls were conducted between 22 April and 6 May. The most recent addition is a poll by Panelbase whose fieldwork was concluded on 6 May.
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.
