Malaysia’s largest party, United Malay National Organisation (UMNO), has begun efforts to reform itself after suffering a shock election defeat last Wednesday that saw its coalition Barisan Nasional whittled down to 78 MPs from a majority of 133 in 2013. Ousted former prime minister Najib Razak has quit UMNO and said his deputy Ahmad Zahid Hamidi, who is also the former deputy prime minister, would take over as the new president UMNO, the main party in the Barisan Nasional alliance. Two reports alleging wrongdoing have been filed against Najib before the country’s anti-corruption commission, as the head of the agency announced his resignation on Monday.
