The Opposition in Papua New Guinea is calling for the establishment of an independent commission against corruption.
The Opposition leader, Peter O'Neill, says the existing Leadership Code is ineffective, and a new body should be set up with powers to tackle corruption in all its manifestations.
Mr O'Neill says the government lacks the willpower and financial commitment to set up the anti-corruption agency.
The Opposition leader describes as inadequate, proposals to institute a maximum penalty for corrupt politicians.
Mr O'Neill says selective prosecution of elected leaders by the Ombudsman Commission is not enough to address the underlying problem.
The government has not immediately been available to respond to Mr O'Neill's comments.
