A shock poll tonight has predicted a landslide 53% victory for Jeremy Corbyn in the Labour leadership race.

The YouGov poll for the Times claims he could smash aside his three contenders in the first round of votes without having to win over second preferences.

It's the second public poll of the leadership race, just 36 hours before the deadline for members and supporters to sign up to vote.

Ladbrokes immediately slashed their odds on the left-winger to 1/2, with Andy Burnham on 3/1 and Yvette Cooper on 4/1.

The poll puts Mr Corbyn an astonishing 32 points ahead of closest rival Mr Burnham.

Despite being in second place the shadow health secretary is trailing on 21%.

Shadow home secretary Yvette Cooper would win 18% of the vote while Liz Kendall would win just 8%.

The lead is far more dramatic than the first YouGov poll last month, which put Mr Corbyn on 43% compared to 26% for Mr Burnham.

That kind of result would force the two frontrunners to fight for second-preference votes from people who would have wanted to pick Ms Cooper or Ms Kendall.

This could have posed a headache for Mr Corbyn - whose outsider badge makes him less likely to pick up second-preference votes.

But if he wins more than 50% in the first round, it'll be enough to carry him through to the top job automatically.

Around 400,000 people are thought to have signed up to vote for Labour's next leader - and just half were part of the party before polling day.

It's sparked fears of mass 'entryism' by hard-left candidates who've stood against Labour in the past.

YouGov said four of the 10 new percentage points voting for Mr Corbyn have switched candidates - the other six have joined afresh in the last month.

YouGov chief Peter Kellner, who faced embarrassment over off-the-mark polls before the election, has put his reputation on the line by predicting a Corbyn 'knockout'.

He writes in tomorrow's Times: "I would personally be astonished if Mr Corbyn does not end up as Labour leader - but I have seldom released a poll with as much trepidation as I have done this time".

The poll questioned 1,411 people eligible to vote in the contest.

It says even fully-fledged Labour members - who've increased from 200,000 to 270,000 since May - would vote 49% in favour of Mr Corbyn.

Registered supporters who've paid £3 to vote are 55% for Mr Corbyn, while affiliated trade union supporters would vote 67% for the left-winger.

He's also more popular with women (61%) than men (48%).

Yvette Cooper's campaign hit out at tonight's result.

A spokesman said: "This does not reflect our extensive phone banking data, which does not suggest any single candidate will receive 50% of first preferences.

"Our figures - as other polls have suggested - show clearly that Yvette is the candidate best placed to draw support from all areas of the Labour Party and win this contest.

"She is best placed to unite the Party and position Labour for victory in the 2020 election."

Today Tony Blair's former press chief Alastair Campbell urged Labour to vote Anyone But Corbyn to stop the 'car-crash' of the left-winger taking office.

And Labour MP Barry Sheerman called for the leadership contest to be halted, warning it was in 'real trouble' over infiltration fears.
