The family of deposed Peruvian president Pedro Castillo has fled to Mexico, which sheltered them.

Mr. Castillo continues to be detained in Peru.

Mr. Castillo’s wife and children were earlier permitted safe passage from the Mexican consulate in Lima to the airport by the foreign minister of Peru.

After Peru ordered him to leave the country within 72 hours, the Mexican ambassador in Lima also departed aboard the same aircraft.

The Peruvian foreign ministry said via its social media channels that it was dismissing Ambassador Pablo Monroy due to “the repeated statements by that country’s top officials on the current situation in Peru.”

Since Peru’s Congress impeached Mr. Castillo on December 7, tensions have increased between the two nations.

Immediately after Mr. Castillo declared a state of emergency and announced he was dismissing Congress, an overwhelming majority of Peruvian parliamentarians voted for his impeachment.

The chairman of Peru’s constitutional court deemed Mr. Castillo’s action a “coup attempt,” and Congress swiftly removed him from office.

He was succeeded by his vice-president, Dina Boluarte, who has urged for the April 2024 elections to be moved up by two years.

The earlier election date was approved by parliamentarians on Tuesday, but it must still be ratified in the coming months.

It is not yet apparent whether the action will be sufficient to stop the violent rallies of Mr. Castillo’s supporters, who are demanding both his release and early elections.

In the hours following his impeachment, Mr. Castillo attempted to claim asylum at the Mexican consulate but was prevented and arrested by his bodyguards.

He is being detained and investigated on suspicion of insurrection and conspiracy.

President Andrés Manuel López Obrador has taken Mr. Castillo’s side, deeming his impeachment undemocratic.

In addition, he authorized his envoy to provide asylum to Lilia Paredes, Mr. Castillo’s wife, and the couple’s children.

In Peru, where Ms. Paredes is under investigation for her alleged ties to a money-laundering operation, this provoked additional outrage.

Maria del Carmen Alva, a Peruvian opposition lawmaker, accused Mexico of “protecting the corrupt.”
