Nauru faces a constitutional crisis after parliament defeated the government's budget on New Year's Eve.
An opposition MP, David Adeang says President Harris should resign because of parliament's refusal to approve the budget.
Mr Adeang claims that President Harris and his cabinet are boycotting parliament to avoid a motion of no confidence
He says President Harris has been responsible for the decline of Nauru to a level of poverty described by some as unseen since World War 2.
President Harris has not been available for comment.
