There are growing concerns in Papua New Guinea the elderly Prime Minister might have to be replaced because of ongoing health problems.
Sir Michael Somare remains in a Singapore hospital after undergoing heart surgery a month ago.
Under PNG law two doctors must be appointed to examine the Prime Minister if he’s sidelined by illness.
Prominent constitutional lawyer John Nongorr, says if Sir Michael can’t resume his duties anytime soon the Governor-General must suspend him from office.
“There should not be a vacuum, there should not be an acting person performing those important functions during a prolonged period.”
The government maintains Sir Michael is on extended medical leave and will resume office.
