A pro-EU anti-Brexit protester holds up a placard showing Britain's Prime Minister Boris Johnson and US businesswoman Jennifer Arcuri in Parliament Square in central London on January 31, 2020 on the day that the UK formally leaves the European Union. - Britain on January 31 ends almost half a century of integration with its closest neighbours and leaves the European Union, starting a new -- but still uncertain -- chapter in its long history.
