BERLIN — German Chancellor Angela Merkel will not lobby for further concessions to be made to the U.K. ahead of any second vote on Prime Minister Theresa May's Brexit deal, a government official in Berlin said Tuesday.

Ahead of a crucial vote in the British parliament on the draft deal — expected to be defeated — British media reported that Merkel told May in a Sunday morning phone call that she would step in to help secure success in any rerun.

"The chancellor has made no assurances beyond what was discussed in the European Council in December and what is laid down in the letter by Jean-Claude Juncker and Donald Tusk," Merkel's spokesperson said Tuesday.

The official said U.K. media reports on the phone call, claiming Merkel is ready to talk again on the terms of the U.K.'s exit, have been "incorrectly reproduced."

The Sun cited a senior British government official as claiming Merkel had agreed “a blood-letting moment” was needed in the Brexit process before further talks could be held.

“Merkel believes there is more the EU can do once the vote is over as no deal would be a disaster for everyone, and they agreed to talk after it," the official said in the Sun article.

Speaking to media in Strasbourg Tuesday, German Foreign Minister Heiko Maas said "there could be further talks" if May's deal was voted down, but that "the agreement stands as it is," Reuters reported. "If there were a better solution, it would already have been put forward.”

U.K. Environment Secretary Michael Gove said earlier he does not "recall any such conversation" when asked on the BBC's Today program whether May had told Cabinet colleagues about an offer from Merkel.
