Indian PM Manmohan Singh has been moved out of intensive care at a Delhi hospital after undergoing heart bypass surgery at the weekend.
Doctors said he was making a "speedy recovery" at the state-run All India Institute of Medical Sciences.
Earlier they said Mr Singh, 76, was expected to resume some official duties within two to four weeks.
But they said it would be up to six weeks before he was fully active.
During the 11-hour operation, surgeons performed five bypasses.
He is expected to remain in hospital for seven to eight days.
Mr Singh previously had bypass surgery in 1990 and an angioplasty in 2004.
He was admitted to hospital on Friday. The operation began at 8.45am local time on Saturday and ended at 5.30pm.
The BBC reports Mr Singh has largely been in good health since he was sworn in as prime minister in May 2004, but recently he underwent prostate surgery and has also had cataract treatment.
The 1991 finance minister is widely regarded as the architect of India's economic reform programme.
