Labour is poised to win the most seats in the Welsh Assembly elections but could just miss out on an outright majority.
A YouGov poll for S4C's Byd ar Bedwar programme found the party's numbers had slipped to 45% in the constituency vote and 41% in the regional vote.
That result could leave Labour just short of a working majority in the Senedd.
Owen Smith, Labour's campaign manager, encouraged voters to turn out for Labour to avoid a Tory-led "losers' coalition".
"We have always said that this election would be a tough fight right until the end and the polling merely reaffirms that," he told Wales Online.
"The choice for Wales is between the certainty that a Labour majority government provides, or a Tory-led losers' coalition.
"The polls show very clearly how vitally important it is for Labour voters to come out on Thursday."
The Welsh Tories are currently sitting on 21% of the constituency vote and 20% of the regional vote, leap-frogging Labour's former coalition partners Plaid Cymru who are on 18% in both.
The Liberal Democrat vote appears to have collapsed, with their polling numbers at eight percent and seven percent.
