MEXICO CITY, Aug 2 (Reuters) - Olga Sanchez, who has been selected as interior minister by Mexico's president-elect, said on Thursday she had resigned from the board of Grupo Financiero Banorte, one of the country's largest financial institutions.
Sanchez said she left the board because she had won a seat in the Senate, which she will assume in September.
Starting in December, she will serve as the interior minister of leftist Andres Manuel Lopez Obrador, who won Mexico's July 1 presidential election in a landslide. In that role, Sanchez will oversee domestic policy and serve as a bridge between the executive and state governments.
Sanchez, a lawyer who served on the Mexican Supreme Court for a decade, joined the board of Banorte in 2016 and was re-elected in 2017.
She said she resigned last week, during the board's latest meeting.
A spokesman for Banorte declined to comment.
Banorte's board is composed of 15 members, 11 of whom, including Sanchez, are classified as independent by Glass Lewis, an influential proxy-advisory firm. (Reporting by Diego Ore and Stefanie Eschenbacher; Writing by Julia Love; Editing by Peter Cooney)
