A YouGov poll for Scotland on Sunday over the Bank Holiday weekend suggests a breakthrough Scottish Parliamentary election result for the Greens, up to seven per cent and ahead of the Liberal Democrats.
Projections from Scotland Votes indicate that the party would be up from two seats to eight. In the Regional vote the poll projects the Scottish National Party (SNP) on 35 per cent, Labour on 33 per cent, the Conservatives on 12 per cent, the Greens on seven per cent, and the Liberal Democrats trailing among the five largest parties on six per cent.
The findings, which reinforce an earlier poll, are all the more remarkable, say commentators, because the Scottish Green Party - despite a vigorous on-the-ground and virtual campaign - has been under-reported in most newspapers and frozen out altogether by the major broadcasters.
Despite complaints, and poll evidence, both STV and the BBC excluded the Greens from the high profile television leaders' debates.
Regarding the latest poll evidence, Scottish Green's co-leader Patrick Harvie declared: "The momentum is clearly with the Greens, and if this poll is right we're on course for our best ever Holyrood result."
He added: "A second vote for the Greens will not only ensure strong voices against the cuts to public services, but if the Lib Dems can be squeezed into fifth place it could even be a fatal blow to this unwanted and unpopular Westminster coalition."
YouGov's results for Scotland on Sunday suggest that in the Constituency vote the SNP are on 42 per cent, Labour 34 per cent and the Conservatives 12 per cent.
The overall seat projections are SNP 54, Labour 47, Conservatives 14, Greens eight and Liberal Democrats five.
The Greens have also been boosted by news that leading Scottish 'Rebus' author Ian Rankin will be backing the party on 5 May 2011.
"Elections aren't won and lost with celebrity endorsements, but it's certainly pleasing to know that Ian Rankin's second vote on Thursday will be for the Greens," said Mr Harvie. "With the polls showing some serious momentum in our direction, we're picking up new members and new voters like never before."
