Labour today hailed a 'stunning result' after increasing its majority by more than 10,000 in a key bellwether seat it was forecast to lose.
Joan Ryan was re-elected after crushing her Tory rival Nick de Bois in Enfield North in the fifth time the two have gone head to head.
Defeated de Bois battered away reporters questions as the scale of his defeat in the seat he held from 2010-2015.
It was a dire result for Conservatives across Enfield as David Burrowes lost Enfield Southgate to Labour's Bambos Charalambous, while Edmonton was held by Kate Osamor with a comfortable majority of over 15,000 Tory Gonul Daniels.
But the Enfield North result was a 'huge shock', the winner said. Ryan told the crowd: "It is a stunning win."
She added: "This was an entirely self serving election. it was arrogant to call an election no one wanted or needed other than Theresa May and the Conservatives."
The Corbyn critic said the party need to 'think hard' on how to capitalise on its shock gains across the country.
De Bois said it it was an 'impressive' result and hinted he would not contest the seat a sixth time.
He said: "Sadly I had one marriage behind me that was unsuccessful. I'm happily married again but [Ryan] is most definitely the other woman in my life.
"It may break your heart but this relationship has come to an end."
In the hours before the result was called Labour campaigners were buoyed by the exit polls suggesting major gains.
Party officials said a surge by left-wing Momentum activists bussed in from other boroughs shored up the doorstep effort in the final days.
Councillor Dino Lemonides, cabinet member for finance at Enfield council, said: "This has been a very strange election.
"Edmonton has always been safe Labour but if we retain Enfield North and take Enfield Southgate it will be because of Momentum's support."
It was clear by 2am that Conservatives were facing defeat as activists and agents dodged questions and stared into their coffee cups.
They blamed the collapse in confidence in Theresa May's and the fall out from the so-called 'Dementia Tax' proposals as losing voters on the doorstep.
One said: "The adult social care disaster was the thing that popped the 'strong and stable' bubble.
"It came up on the doorstep all the time. It was a disaster.
"We also had demographic changes in the constituencies with a larger youth vote turning out and people opposing Brexit.
"But it all cane down to the adult social care policy. That changed everything."
The turnout in Enfield North was 71 percent, an increase on 2015 by four percent.
