A university graduate who bet £10,000 on Jeremy Corbyn and his party to win the general election says he is 'completely certain' of a Labour victory.

Bookmaker Betfred said the 24-year-old, from Norwich, placed three bets on the outcome of next month's vote at its London Road shop last Thursday.

The political punter, who has chosen to remain anonymous, revealed he was a biology graduate and a Norwich City fan, who saved up enough money for the bet during university.

He told Betfred: 'No one knows about this bet. No one in my family, no friends, no one at all. I want to keep it that way especially if, as is unlikely, I fall flat on my face.'

On Thursday, he placed £6,000 on Labour Party leader Mr Corbyn becoming the next prime minister at 12/1 odds.

He bet a further £3,000 on Labour to win the most seats at 20/1.

And £1,000 - at 40/1 odds - on Labour to achieve the majority of seats in parliament next month.

Should all three of his bets come off, he will see a £182,000 return for his money.

The mystery punter told Betfred that he was 'crazy about Labour', and intended to campaign for the party in the run up to the June 8 election.

He said: 'I joined the Labour party so I could vote for Jeremy Corbyn. He is a most sound politician, so socialist, a person who would look after us all.

The man said he had previously placed smaller bets on football, but lost. However, he said he was 'absolutely completely certain' Labour would win.

'This time I decided to go big on something I know about,' he said. 'When I was at university and not doing casual work I watched as many programmes about politics as I could.

'If I do win it will set my life up nicely and I will celebrate by taking myself off with friends on a holiday in Greece, which is my favourite place.'

The man said he accumulated the £10,000 by working as a barman and waiter almost every night for four years while at university.

When Mr Corbyn visited the county over the weekend, he wished the punter well and hoped that he put the money towards a 'good cause'.

The bet is thought to be the joint-largest made in the country on the Islington North candidate to win the election.
