DESPITE REPORTS earlier this week that Sir Michael Somare would be returning to PNG within days, and even resuming his role as prime minister, there are growing concerns that he might have to be replaced because of continuing health problems.

Sir Michael remains in a Singapore hospital after undergoing heart surgery a month ago.

Constitutional lawyer John Nongorr says if Sir Michael can't resume his duties soon the Governor-General must suspend him from office. Under PNG law two doctors must be appointed to examine the prime minister if he's disabled by illness.

"There should not be a vacuum, there should not be an acting person performing those important functions during a prolonged period,” said Dr Nonggorr.

The government says Sir Michael is on extended medical leave and will resume office.
