The UK is no longer a member of the European Union, after 47 years of membership. The historic moment, which happened at 23:00 GMT, was marked by both celebrations and anti-Brexit protests.
UK Prime Minister Boris Johnson marked the historic moment with his team at his Downing Street office.
In a message released on social media an hour before the UK’s departure, Prime Minister Boris Johnson said: “For many people this is an astonishing moment of hope, a moment they thought would never come. And there are many of course who feel a sense of anxiety and loss. And then of course there is a third group – perhaps the biggest – who had started to worry that the whole political wrangle would never come to an end.
I understand all those feelings and our job as the government – my job – is to bring this country together now and take us forward.”
“The most important thing to say tonight is that this is not an end but a beginning and a moment of real national renewal and change, he added.
The European Parliament approved Brexit agreement on January 30.
