Malaysian leader Anwar Ibrahim found guilty in sodomy trial
The Federal Court's judgement upholds a ruling by the Court of Appeal in March last year, which found the 67-year-old guilty of sodomising a former political aide.
He is expected to be sentenced later on Tuesday.
Sodomy is illegal in Muslim-majority Malaysia where the offence carries a jail term of up to 20 years.
