Jeremy Corbyn has almost eliminated the gap on Theresa May as to who would make the best prime minister.
The Labour leader, who is currently on holiday in Croatia, is just three points behind May, who limped on to summer recess to avoid a coup by her rebellious MPs.
One third of voters (33 per cent) said Corbyn would make the best prime minister while May was judged the better option by 36 per cent, according to the YouGov poll for The Times.
When the survey was last carried out it showed May with a five point lead over her socialist rival.
Over a longer period it marks striking progress for Corbyn who was 20 points behind May on capability in April.
The Tory leader’s position is seen as having stabilised slightly after she promised her backbenchers that she would get them out of the “mess” she had created with her botched handling of the snap election.
Corbyn has vowed to spent the rest of the summer touring key marginal seats.
