THE SNP would win all but two of Scotland's 59 seats, according to projections from the latest poll.
The TNS snapshot put support for the Nationalists at 54 per cent, up two points from the previous poll, compared to 22 per cent for Labour, which was down two points.
Support for the Conservatives was unchanged at 13 while the Liberal Democrats held at six, the Greens were down one at two points and Ukip were up one at two points.
Using the poll data, the psephological website ScotlandVotes predicted Labour and the Liberal Democrats would win just one seat each with only Willie Bain for the former and Alistair Carmichael, the Scottish Secretary, for the latter surviving the SNP surge.
The TNS survey of 1003 adults in Scotland also asked people who they felt would "try to get the best deal for Scotland at Westminster".
Some 42 per cent said Nicola Sturgeon while just eight per cent said Jim Murphy and three per cent Ed Miliband. At seven per cent, David Cameron scored higher than Alex Salmond on six.
The poll, conducted between April 1 and 19, also showed more than two-thirds of people - 67 per cent - said they were certain to vote; higher than the rest of the UK at 62 per cent. SNP supporters were the most likely to say they were certain to vote at 82 per cent.
Among those certain to vote, 29 per cent were undecided.
Angus Robertson, the SNP campaign director, stressed his party was taking nothing for granted but noted: "This poll is yet another welcome indication that the momentum in this campaign continues to be with the SNP; more and more people are putting their trust in the SNP to make Scotland's voice heard at Westminster, end the cuts and stand up for progressive politics across the UK."
Tom Costley, head of TNS Scotland, said: "Nicola Sturgeon and the SNP appear to be going from strength to strength."
He added: "It remains to be seen what impact the 29 per cent, who claim to be undecided as to which way to vote, will have on the total number of Westminster seats gained by the SNP."
Meantime UK-wide, an Ashcroft weekly snapshot placed the Tories up two points on 36 per cent, Labour unchanged on 30, Ukip down two on 11, the Liberal Democrtas down one on nine, the Greens up three on seven and the SNP down two on four.
