Labour has increased its support among men to almost close the gender difference it habitually records in polls.
But it appears to have lost support among the elderly, according to the last Herald-DigiPoll survey before tomorrow's election.
Labour's overall party vote is up by 1.3 points to 25.9 per cent.
But a breakdown in the figures shows its support among men has climbed to 25.4 this week, from 21.2 the week before, and 18.4 per cent the week before that.
It has the support of 26.2 per cent of women. Labour has also picked up support among young voters.
