'Just add water': Johnson on Brexit deal

Britons will vote on Dec. 12 after parliament agreed to an early election, seeking to end three years of deep disagreement over Brexit that has sapped investors' faith in the stability of the world's fifth largest economy and damaged Britain's international standing.

"All we need is a working majority. All we need is a working majority in parliament to make parliament work. Just nine more seats. Just nine more seats and we can deliver Brexit in January and get parliament working for you and unleash the potential of the whole country," he added as he spoke at an electric car manufacturer in Coventry.

Johnson, 55, hopes to win a majority to push through the last-minute Brexit deal he struck with the European Union last month after the bloc granted a third delay to the divorce that was originally supposed to take place on March 29. Most voters who took part in a June 2016 referendum voted in favour of the UK leaving the EU.

The first December election in Britain since 1923 will be one of the hardest to forecast in years. Brexit has scrambled voters' traditional loyalties and is giving smaller rivals a chance to challenge the two biggest parties, Johnson's Conservative Party and the left-of-center Labour Party led by Jeremy Corbyn.
