The table shows that the polls were very accurate for estimating the Conservative-Labour lead. Both the pollsters and the betting markets overestimated the vote share of the Lib Dems by about 3%. Ipsos-MORI was clearly the most accurate pollster at this election, and Angus Reid was the least accurate.

The polls generally underestimated both Labour (particularly) and the Conservatives and over-estimated the SNP and the Liberal Democrats. Ipsos-MORI was the least successful pollster in this regard, estimating the Labour-SNP lead at 10% when it turned out to be 22%, though their last Scottish poll was taken three weeks before polling day.
