Honduras will sign an agreement Thursday to install a United Nations-backed anti-corruption mission in the country, a foreign ministry official said Wednesday, making good on a key campaign pledge of President Xiomara Castro to root out graft. Castro met with U.N. Secretary General Antonio Guterres in New York earlier on Wednesday, wrapping up talks which began in May to create the anti-corruption commission known as CICIH, her office said in a post on social media.
