Negotiations for a trade agreement between the European Union and the United Kingdom have been halted.

European negotiator Michel Barnier and his British counterpart David Frost announced this via Twitter.

According to them, there are still big differences.

Barnier and Frost are going to inform their bosses about the state of the negotiations.

European Commission President Ursula von der Leyen and British Prime Minister Boris Johnson will then meet on Saturday afternoon.

The negotiations have been halted because there is still a great distance between the two sides in the areas of state aid, supervision and fisheries.

Those have been the three stumbling blocks for some time now.

The United Kingdom officially left the European Union on January 31, 2020.

Since then there has been a transitional period in which the same rules are applied for mutual trade as for departure.

This transition period ends on December 31.

Before then, the UK and the EU want to reach an agreement on the mutual trade relationship.
