Anti-corruption campaigner wins Guatemala presidential election by landslide

Bernado Arevalo's victory comes amid growing concerns over state of democracy in Central America

The Guatemalan anti-corruption crusader Bernardo Arevalo has been voted in as president, according to preliminary results, a victory that until recently seemed impossible and which many voters hope will end years of rule dogged by allegations of corruption and authoritarianism.

Arevalo, a 64-year-old ex-diplomat and son of a former president, had a 58% to 37% lead over the former first lady Sandra Torres with 99% of votes counted.
