As security dominated the closing stages of the U.K. election campaign, Prime Minister Theresa May said on Tuesday that she would be willing to tear up human-rights legislation to combat terrorism, a move that the Labour opposition said was an attempt to distract from her cuts to police.

The prime minister and her Labour Party opponent, Jeremy Corbyn, set out on whistle-stop tours of the country ahead of Thursday¡¯s vote, with polls all showing May¡¯s Conservatives ahead but disagreeing about whether the race is close.

Privately, Labour aides and candidates were preparing to lose seats.
