Vanuatu's prime minister, Sato Kilman, wants the National Constitution amended.
Mr Kilman's made the call following today's adjournment of the extraordinary session of parliament.
Mr Kilman says Vanuatu needs to amend its constitution in order to prevent MPs from crossing the floor and changing political parties, which he says has resulted in the waste of public money.
Mr Kilman's also calling on the public to support the government and the opposition if the government makes a proposal to amend the constitution.
Our correspondent says last year the government spent more than a million US dollars compensating politicians when Mr Kilman's government replaced that of the former prime minister, Edward Natapei.
If parliament votes for the motion against Mr Kilman on Monday, it's expected the government will spend the same amount again in compensation.
