The UK's divorce from the European Union (EU) came into force on Friday night as it became the first country to exit the economic bloc after 47 years of membership following the vote in favour of Brexit in June 2016.
British Prime Minister Boris Johnson hailed the historic moment as the dawn of a new era for the UK in his address to the nation just before Brexit.
Brexit came into force at 11:00 pm (2300 GMT).
"This is the moment when the dawn breaks and the curtain goes up on a new act in our great national drama," said Johnson, in his video message which promised hope and opportunity to every part of the United Kingdom.
"It is not just about some legal extrication. It is potentially a moment of real national renewal and change. This is the dawn of a new era in which we no longer accept that your life chances -- your family's life chances -- should depend on which part of the country you grow up in," he said.
