Jeremy Corbyn has gained eight points on the Tories – in a poll that is usually among the least favourable to Labour.
The party has slimmed down the Conservative lead to only 15 points.
Jeremy Corbyn’s personal favourability – often held as the biggest problem for Labour to win the election – has also improved, according to the new data.
The findings come from new polling by Ipsos MORI – a polling company that tends to be among the least favourable to Labour’s chances – published by the Evening Standard.
They came on the same day that Labour shot to its best polling since the election campaign began.
The poll shows the Conservatives on 49 per cent and Labour on 34 per cent.
Tony Blair won a majority in 2005 with 35 per cent of the vote – just one percentage point more.
