Former PNG PM

Sir Mekere died after a long illness in Australia last month, aged 74.

Those at the public viewing included Prime Minister James Marape as well as Sir Michael Somare, who was the country's first prime minister after independence in 1975, as well as members of the diplomatic corps.

A state funeral will be held on Friday before his burial at Independence Hill.

Sir Mekere's body was flown back from Australia last week after a service in Brisbane attended by his immediate family.

PNG's police commissioner, David Manning, last week said the warrant was issued for the Ialibu-Pangia MP's arrest in relation to an alleged corruption case.

Subsequently, the court granted an interim injunction on moves to arrest him. Mr O'Neill's legal team claimed he would likely suffer "irreparable damages" caused by a "defective" warrant.

The head of the police fraud squad, Matthew Damaru, said the legal move was similar to when Mr O'Neill's lawyers challenged a previous warrant for his arrest issued in 2014 in a separate corruption case.
