This is stated in the statement of the head of the press service of the European Commission Eric Mamer on his Twitter page.

"After the announcement of the UK, Deputy Chairman of the European Commission Maros Sefcovic leaves for London ... for an emergency meeting of the Joint Committee on Brexit," - said in a statement.

As TASS clarifies, this trip is associated with the publication by the British government of a bill that violates the agreement between Brussels and London on the terms of a European divorce following Brexit.

Earlier, British Prime Minister Boris Johnson said that London would withdraw from negotiations on a trade agreement with the EU if the parties fail to reach a compromise.
