The SNP has extended its lead over Labour, according to a new poll on general election voting intentions.
The TNS poll shows support for the nationalists at 46% while Labour trails on 30% ahead of the May vote.
This compares with 41% support for the SNP and 31% for Labour identified by the same pollsters earlier this month.
Meanwhile, in the latest poll, 14% back the Tories, 4% back the Greens, 3% support the Liberal Democrats and 3% would opt for Ukip.
A total of 1,001 adults were interviewed between January 30 and February 22.
The new poll shows the SNP has increased the gap with Labour from 10 percentage points to 16 in just a few weeks.
Angus Robertson, the SNP's general election campaign director, said: "This poll shows an increased lead for the SNP - but we are taking absolutely nothing for granted and will work hard for every vote and seat in May.
"The key issue in May is who will best represent the people of Scotland - and the general election is a wonderful opportunity for Scotland to have power by electing a strong team of SNP MPs to a hung parliament at Westminster.
"Labour are paying a huge price for their toxic referendum alliance with the Tories - which to all intents and purposes has continued.
"In recent days, we have seen senior Labour figures try and urge Scots to vote Tory and Lib Dem - no wonder more and more Scots are rejecting Labour and putting their trust in the SNP."
