Bookies last night shortened the odds on Labour winning the General Election
Theresa May remains favourite to stay on in Number 10 on 1/4.
Fellow Tory Boris Johnson is considered her main rival at 25/1 – down from 100/1 last week.
Jessica Bridge, of Ladbrokes, said: “Neither leader performed particularly badly or well during Friday night’s debate.
However, bets continue to flood in for Labour and while their odds have contracted to their shortest price yet, it still only represents a 17 per cent chance of pulling off a shock victory.
“Perhaps the most interesting market to watch over the past couple days is the odds of Boris Johnson being Prime Minister on July 1.
"The Foreign Secretary has become more visible in recent days and his odds have dropped from 100/1 to 25/1 – including one wager placed in a shop in Chelsea to the tune of £2,000.
