Manuel Mondragon was confirmed by the Senate as Mexico's national security commissioner, a new post created by President Enrique Peña Nieto.
The new post is an "enormous responsibility," but "there will be results" in "resolving the country's security issues," Mondragon told Radio Formula.
Mondragon will be in charge of the Federal Police, which was previously under the defunct Public Safety Secretariat, and the new National Gendarmerie, a 10,000-member law enforcement agency expected to be launched at the end of this year.
He will also be responsible for managing the federal prison system and Plataforma Mexico, a database holding law enforcement information.
Mondragon was confirmed Tuesday on a vote of 115-0, with two abstantions, in the Senate.
The former Mexico City police chief will run the National Security Commission, a Government Secretariat agency.
Mondragon was the first security official confirmed by the Senate since Dec. 13, when Congress approved legislation giving the Government Secretariat more powers and making it the lead agency in fighting the war on drugs.
The national security commissioner, who was sworn in on Tuesday, is a surgeon who holds the rank of rear admiral in the navy medical corps.
Mondragon has held a number of federal posts and served as Mexico City's police chief until Nov. 30. EFE
