Labour Leader Jeremy Corbyn outperformed expectations in a crucial television debate against Prime Minister Boris Johnson, ahead of the U.K.'s general election on Dec. 12.
The opposition leader, who has been lagging behind Johnson in personal approval ratings, almost tied with the prime minister in a snap poll on which candidate won the contest on Tuesday night.
The YouGov/Sky News survey of 1,600 people gave Johnson the narrowest victory, with 51 percent saying he won the debate, against 49 percent saying Corbyn performed best.
