JEREMY CORBYN romped home to a thumping 33,000 majority in his north London constituency — and vowed to fight to implement Labour’s radical plan for Britain.

The party leader received a hero’s reception at the election count in the small hours of yesterday. His tally of 40,086 — a 75 per cent share of the vote — was the highest ever received in Islington North.

His majority of 33,215 was also among the highest in Britain. Mr Corbyn praised voters for putting their trust in him and other Labour candidates.

“You know what? Politics has changed,” he said. “Politics isn’t going back into the box where it was before.

“What’s happened is, people have said they’ve had quite enough of austerity politics, they’ve had quite enough of cuts in public expenditure, underfunding our health service, underfunding our schools, our education service, and not giving our young people the chance they deserve in our society.”

In the hall, there were smiles all round. The young counting staff were clearly enraptured by Mr Corbyn’s presence, whispering among themselves and posing for selfies.

The grins of Islington’s Labour stalwarts confirmed the widespread relief that the party leader’s speech would be one of triumph, rather than of defence.

And then there was Michael Foster, the man who took Mr Corbyn to court in an attempt to keep him off last year’s leadership ballot.

Having stood against him on the platform of “Labour for the Common Good” and garnered a measly 208 votes, he was at least gracious in defeat.

This tally still dwarfed that of Communist League candidate Andres Mendoza, who picked up just seven votes.

The Socialist Party of Great Britain’s Bill Martin took 21 — but his was, after all, the only party on the ballot that requires prospective new members to sit an entrance exam.

Outside the sports centre, crowds had gathered to sing the winner’s praises. “Oh, Jerem-y Cor-byn,” they roared to the tune of the White Stripes’ Seven Nation Army.

In neighbouring Islington South and Finsbury, shadow foreign secretary Emily Thornberry retained her seat with a huge 20,263 majority.

She strongly praised Mr Corbyn in her victory speech and said he would be “too modest” to take any credit himself.

“I cannot remember a politician in Britain who has put up with so much,” she said. “The one who’s been strong and stable has been Jeremy Corbyn.”
