The YouGov survey conducted for The Times newspaper and published on Friday found that 35 per cent of respondents voted for Corbyn and thought that the Labour Party leader would be the best choice for the country’s prime minister.
The poll found the incumbent premier one point behind on 34 per cent, while 30 per cent of those surveyed said they were unsure. A total of 1,670 people took part in the survey.
This is the first time Corbyn is ahead in a poll asking who would be the best prime minister.
It comes at a time when May faces intense pressure following a disastrous general election in which the Tories lost their parliamentary majority and threw the country into political turmoil.
The embattled PM, who called for the snap vote in mid-April to get “a stronger hand” in the Brexit talks, is now trying to form a minority government with Northern Ireland’s Democratic Unionist Party (DUP).
A similar poll by the YouGov on the eve of the June 8 election discovered that 43 per cent of voters believed May would make the best prime minister, while 32 per cent opted for Corbyn.
The British Conservative Party leader is also under fire over safety and security of the country in the wake of the recent Grenfell Tower tragedy and terrorist attacks. Police have confirmed at least 30 are dead in the Grenfell incident, but there are still more than 70 unaccounted for, raising the fears that the final death toll might cross 100.
