A little later, the British flag will also be taken down in front of the European Council and the European Parliament in Brussels.
At 23 GMT today, the UK leaves the European Union after 47 years of membership. Thus, the bloc will remain with 27 members. This is the first time a Union member has left the country since its creation.
By the end of 2020, EU citizens are not expected to undergo major changes, as a Transition Period will be introduced. Travel rules remain unchanged throughout the Transition Period. There will be no change in the rights of Bulgarian citizens in the UK in terms of work either.
