For Johnson, whose 20-week tenure in power has been marked by chaotic scenes in parliament and stark division on the streets over Britain's tortuous departure from the European Union, the victory in Thursday's contest is vindication.
The long-delayed Brexit is likely to become reality soon with Prime Minister Boris Johnson's Conservative Party recording a resounding victory in Britain's election.
A landslide victory for the Conservative Party would mark the ultimate failure of opponents of Brexit who plotted to thwart a 2016 referendum vote.
An exit poll showed the Conservatives winning a landslide 368 seats, more than enough for a comfortable majority in the 650-seat parliament and the biggest Conservative national election win since Margaret Thatcher's 1987 triumph.
"I think this will turn out to be a historic election that gives us now, in this new government, the chance to respect the democratic will of the British people," Johnson said after winning his seat of Uxbridge.
He said the Conservatives now had a powerful new mandate to get Brexit done.
With results from across Britain indicating the exit poll was accurate, Johnson's bet on a snap election has paid off, meaning he will swiftly ratify the Brexit deal he struck with the EU so that the United Kingdom can leave on Jan. 31 - 10 months later than initially planned.
