Convicted of corruption less than a month ago and sentenced to 12 years in jail, former prime minister Najib Abdul Razak was back campaigning for a party candidate over the weekend in a by-election for a state assembly seat.

Out on bail, Najib is waiting for his appeal date to be set, while standing accused in two other trials and waiting for two more to begin - mostly linked to the looting of billions of dollars from defunct sovereign fund 1Malaysia Development Bhd (1MDB).
