Indonesian ex-leader Suharto's health has worsened and is now "critical", his doctors have told the country's President Susilo Bambang Yudhoyono.
Suharto was in power for more than 30 years
Mr Suharto, 86, was taken to hospital on Friday with symptoms of anaemia and low blood pressure. He deteriorated that night but has since stabilised.
He has been put on kidney dialysis and needs a second pacemaker operation.
Mr Suharto took power in 1966 and ruled Indonesia with an iron fist for a total of 32 years.
He and his family deny reports that they stole billions of dollars while he was in power.
President Yudhoyono was speaking after visiting Mr Suharto on Saturday.

"The team of presidential doctors... explained that his condition is critical. We have to do what we can do to restore his health. We should pray for the best," he said.
Some 40 medical specialists are said to have been assembled to assist with Mr Suharto's care.
His six children and officials from his era in power were reportedly among the stream of high-profile visitors to his bedside in hospital.
Mr Suharto has lived quietly in Jakarta since being overthrown in 1998 amid political upheaval and an economic crisis.
But although accused of embezzling huge sums from state funds during his three decades in power, his lawyers have always successfully pleaded that his failing health meant he should not stand trial.
Mr Suharto has been in and out of hospital in recent years with a series of health problems, including a stroke.
