Mexico union leader Elba Esther Gordillo arrested

Union head Elba Esther Gordillo, known as Mexico's most powerful woman, has been arrested on corruption charges.

Ms Gordillo, who runs the 1.5 million-member Mexican teachers' union, is alleged to have embezzled more than $156m from union funds.

No-one from her legal team has responded to the allegations, but in the past she has denied any wrongdoing.

Her arrest came a day after the government enacted major reforms to the education system.

President Enrique Pena Nieto signed the sweeping reforms, which seek to change a system dominated by Ms Gordillo's union in which teaching positions could be sold or inherited.

For more than 20 years she has led the National Union of Education Workers (SNTE).
