A court in Guatemala has sentenced the former vice-president, Roxana Baldetti, to 15 years and six months in jail for her role in what became known as the "Magic Water" scandal.
Prosecutors said that she embezzled millions from a state fund set up to decontaminate a lake.
The chemical formula used as part of the clean-up was an ineffective solution of water, salt and chlorine.
The deal was negotiated by her brother, Mario, who held no official post.
He was sentenced to 13 years in jail.
