Leftist Lopez Obrador sworn in as Mexico president

MEXICO: Anti-establishment leftist Andres Manuel Lopez Obrador vowed a "deep and radical" change in Mexico as he swore in as the country´s president Saturday, after winning a landslide election victory.

The leader, widely known by his initials as "AMLO," took the oath of office and donned the presidential sash before Congress -- where the coalition led by the upstart party he founded four years ago, Morena, now has strong majorities in both houses.

Ending 89 years of government by the same two parties, Lopez Obrador surged to victory in the July 1 elections promising a new approach to issues fueling widespread outrage: crime, poverty and corruption.

But not everyone is persuaded: critics say the sharp-tongued, silver-haired leader has a radical and authoritarian streak. And despite his promises of business-friendly policies, Mexican stocks and the peso have plunged in recent weeks.
