The Mexican state governor of Puebla and his wife, a lawmaker who was former governor of the same state, died in a helicopter crash on Monday, according to Mexican officials and news media reports.
The governor, Martha Erika Alonso, took office 10 days ago. She is the first female governor of her state.
His wife, Rafael Moreno Valle, is considered a revolutionary political center of the center-right National Action Party. He administers Puebla, in central Mexico, from 2011 to 2017, and at one point is cited as a possible presidential candidate.
President Andrés Manuel López Obrador, whose July elections promoted the political establishment of the country, offered his "deepest sympathy" to their families on Monday and the government ordered to see what had happened .  "I was working to investigate the causes of the accident; to tell the truth about what happened and act accordingly," wrote the president, a member of the Morena party.
In a statement, the Puebla state government said that at least five people died in the crash, including the governor and his wife. The other three men named were two captains, Roberto Coppe Obregón and Marco Antonio Tavera Romero, and a senator assistant, Héctor Baltazar Mendoza.
The statement described the crash as a "disaster" and said it occurred in the municipality of Coronango.
Mr. Moreno Valle won the presidency of Puebla in 2010 and rose to become a strong leader, close to Mexico's former president, Enrique Peña Nieto. As his ambition grew, the critics of Mr. Moreno Valle, he has been strengthened with the bad steps to keep the state of Puebla – including members of his own party – under control.
In those years, he was accused of the political process. The election of his wife in governorship was disputed by the party of Mr. López Obrador, claiming that it had been manipulated by Mr. Moreno Valle to give power to his wife, reported The Associated Press.
Ms. Alonso in the latter swore on December 14 .
Vicente Fox, who won the Mexican presidency as a member of the National Action Party, tweeted "It fills me with sadness suddenly losing two talented friends with brilliant political races and stars of opposition. "
Mr. Fox asked for an investigation.
