A United Nations judge has been jailed for six years and four months after being convicted of forcing a young Ugandan woman to work as a slave in Britain. Lydia Mugambe, 50, was found guilty of conspiring to facilitate the commission of a breach of UK immigration law, facilitating travel with a view to exploitation, forcing someone to work, and conspiracy to intimidate a witness after a trial at Oxford Crown Court. The trial was told Mugambe forced her victim, who cannot be named for legal reasons, to work as her maid and provide free childcare while preventing her from holding down steady employment. Mugambe took "advantage of her status" as a judge over her victim in the "most egregious way" and tricked her into coming to the UK, the court heard. Image: Lydia Mugambe.
