The European Union urges the UK to adhere to the agreements reached during the first phase of negotiations on Brexit process, DW reported.

"We will not tolerate if these results are questioned," EU chief negotiator Michel Barnier said.

“There is no going back on this sufficient progress, this progress has been noted and recorded and is going to be translated into a legally binding withdrawal agreement” he said.

It should be noted that the agreements, signed on December 8 between European Commission President Jean-Claude Juncker and British Prime Minister Theresa May marking the end of the first phase of talks, must be approved by the heads of state and government of the EU.

The comment from EU chief negotiator Michel Barnier came after UK Brexit Secretary David Davis suggested the divorce agreement unveiled by Theresa May amounted to a "statement of intent" rather than a binding agreement.
