Guatemalan President-elect Bernardo Arevalo is due to be sworn in Sunday for a four-year term, pledging to banish deep-rooted corruption, though he will come up against a divided Congress and string of judicial attempts to block him from wielding power. Vowing to restore democracy in Guatemala, the most populous country in Central America with 17.1 million people, Arevalo, 65, won the August presidential run-off in a sweeping victory. In the months after, Guatamala's attorney general - seen as an ally of outgoing President Alejandro Giammattei - has intensified attempts to discredit Arevalo's victory and hinder his transition.
