Ed Miliband's personal rating has overtaken David Cameron's for the first time, according to a poll on Sunday.
Research by ComRes for the Independent on Sunday and Sunday Mirror found the approval score for the Prime Minister had slumped by seven points since last month.
By contrast, the Labour leader's had increased by 12.
Overall Miliband's party was on 41%, with the Tories on 32% and Liberal Democrats 11%.
Some 26% of those surveyed agreed that Mr Cameron was turning out to be good premier, down three points from April 22.
But 54% said the opposite - giving him a net rating of minus 28.
Miliband's score improved to minus 19, as his approval rose eight points to 26% while 45% thought he was doing a bad job.
The Tories and Labour were deadlocked on who was most trusted to run the economy, both receiving a rating of minus 29.
ComRes interviewed 2,038 adults online on May 16-17, it said.
