KUALA LUMPUR: Malaysia's top court on Saturday condemned as a smear attempt the leaking of an alleged guilty verdict against the wife of former prime minister Najib Razak, days after he was imprisoned for graft linked to the looted 1Malaysia Development Berhad (1MDB) state fund.

The Southeast Asian country's High Court is due to deliver its verdict next Thursday in Rosmah Mansor's graft trial over a 1.25-billion-ringgit ($279-million) solar energy project. Najib began a 12-year prison term on Tuesday after losing his final appeal in one of the five graft cases against him involving 1MDB.
