LONDON (Reuters) – Prime Minister Boris Johnson called on Friday for unity to heal the Brexit divisions that have riven the United Kingdom, hours after winning a commanding victory from voters who backed his bid to deliver on the EU divorce by the end of January.

The face of the victorious “Leave” campaign in the 2016 referendum, Johnson fought the election under the slogan of “Get Brexit Done”, promising to end the deadlock and spend more on health, education and the police.

Results from the 650 parliamentary constituencies around the United Kingdom showed that Johnson’s Conservative Party had trounced its main opponent, winning 365 seats to the Labour Party’s 203, the best win for the Conservatives since 1987.

“I frankly urge everyone on either side of what are, after 3.5 years, an increasingly arid argument, I urge everyone to find closure and to let the healing begin,” Johnson said outside Downing Street.

“I know that after five weeks, frankly, of electioneering, this country deserves a break from wrangling, a break from politics and a permanent break from talking about Brexit.”

Labour had its worst election defeat since 1935.

Johnson’s landslide Conservative win marked the ultimate failure of opponents of Brexit who plotted to thwart a 2016 referendum vote through legislative combat in parliament and prompted some of the biggest protests in recent British history.
