Police in Papua New Guinea have issued a call-out for troops to help in the security clampdown in the capital, Port Moresby, from Saturday.
This is part of a security operation ahead of Monday's election of a new prime minister.
The security arrangements include a ban on MPs carrying firearms in parliament.
Private security of MPs in hotels will be replaced by police and troops.
Papua New Guinea's first prime minister, opposition politician Sir Michael Somare, has been asked to try and form the next government after his party won the most seats.
