How did Brexit impact on EU and UK?

EU countries and Britain are having a number of conflicts these days.

 Britain will send two patrol ships into the English Channel to its island of Jersey after France threatened to cut off electricity there to protest changes in fishing conditions after Brexit.

British Prime Minister Boris Johnson discussed with the Jersey authorities the possibility of a French blockade of the island, CNN reports. The politician declared his continued support for Jersey and stressed that any blockade would be completely unlawful, a government spokesman said.

At the same time, Johnson noted the need to de-escalate tensions between Paris and the Jersey administration.

The European Union and the United Kingdom have finally completed all formalities in the European process for the United Kingdom's withdrawal from the community (Brexit). At 00:00 on May 1, Brussels time, an agreement on bilateral relations between the UK and the EU entered into force.
