The judge agreed to continue the proceedings on July 17, after Najib’s lawyer submitted a request to vacate the trial on Thursday due to a foreign ministry meeting he had to attend.
The lawyer then requested a later resumption to let Najib join the Chini state seat by-election campaign this week and attend a parliament session set to begin July 13.
The trial revolves around corruption and money-laundering charges involving US$681 million that appeared in Najib’s personal bank accounts.
Following political turmoil in February, Najib’s party has since returned to the ruling administration, spurring concern over the ongoing 1MDB trials and investigations.
Current Prime Minister Muhyiddin Yassin has pledged to continue fighting corruption, even as his government faced a backlash for agreeing to a settlement with Najib’s stepson in a separate case involving 1MDB funds.
