The president is scheduled to be in Indonesia’s capital Jakarta tomorrow. Mahfud did not say why he would be stepping down from the job.

Mahfud is the running mate of former provincial governor Ganjar Pranowo, who is up against defence minister Prabowo Subianto, and ex-Jakarta governor Anies Baswedan.

“I will say my goodbye to the president with honour. I will report to him that I am done (with the job),” Mahfud said in a statement livestreamed on his Instagram account.

The office of the president did not immediately respond to a request to comment.

Indonesia is to have its presidential and legislative elections on Feb 14.

Mahfud’s resignation comes amid speculation and reports in local media about the potential resignation of respected finance minister Sri Mulyani Indrawati.

The finance ministry has said Sri Mulyani is continuing to carry out her duties in managing state finances.

Opinion surveys show the pairing of Ganjar and Mahfud in last place in the race to lead the world’s third-largest democracy, just lagging another candidate Anies Baswedan, but well behind clear frontrunner Prabowo, whose running mate is President Widodo’s son.
