Mexico’s president has postponed his plans to visit the United States after a bad-tempered telephone conversation with President Donald Trump.

Mr Trump refused to back down on his border wall rhetoric, according to sources in both countries, leading the exasperated Mexican president to decide against an imminent White House encounter.

Mexico is usually one of the first stops for any new president, but Mr Trump is yet to visit as leader, and his Mexican counterpart has not travelled to Washington.

On Tuesday, Enrique Pena Nieto spoke to Mr Trump in a 50-minute call in which it was expected that they would lay the foundations for a visit in March. Prior to their conversation, on February 14, Luis Videgaray, Mexico’s foreign minister, travelled to Washington and believed he had secured assurances that Mr Trump would not broach the subject of the wall when Mr Pena Nieto visited.

But Tuesday’s conversation did not go well, both sides told The Washington Post.

Mr Trump said he would not be bound by any such agreement and could not commit himself to not talking about the wall.

“That was a dealbreaker for us,” a Mexican official said, adding that Mr Pena Nieto and his administration were concerned in particular about a reporter asking a question about funding for the wall at a news conference and Trump answering it.
