After winning his seat back in Islington, North London, early on Friday, 68 year-old Corbyn called for May to step down. “People have said they have quite enough of austerity politics,” he said in a speech. “The PM called this election because she wanted a mandate. Well, the mandate she’s got is lost Conservative seats, lost votes, lost support and lost confidence.”

Betting exchange Betfair said that Corbyn was the favorite to become U.K. Prime Minister, Reuters reported.

In a speech on Friday, May said it will be incumbent on her party to offer stability if Conservatives win the most seats.

SNP leader Nicola Sturgeon called the early results “disastrous” for PM May and expressed disappointment over the SNP’s performance, Reuters said.
