Support for Labour is plummeting, according to new voter research.
The latest Guardian ICM opinion poll puts the Tories on 40%, the party's highest rating in the newspaper's surveys since March 2010 and five points ahead of the Opposition.
Separate research carried out by Populus for The Times sees Labour on 38 points, down one since December, while the Tories gained two taking them to 37.
It also reported the number of voters who "find it difficult to imagine Ed Miliband running the country as prime minister" was growing - up from 63% in September to 68% in the latest survey.
Populus interviewed 1,503 adults while ICM Research surveyed 1,003 adults. Both polls were carried out between January 20-22.
