Prime Minister 'Akilisi Pohiva has launched a crusade against people involved in the illegal sale of Tongan passports, which he claims have been used to smuggle drugs to New Zealand and elsewhere.
A police taskforce was established last year to investigate and is receiving help from New Zealand's Serious Fraud Office.
About a dozen lower-level Government officials have been arrested but Pohiva wants his predecessor, current Speaker of Parliament Lord Tu'ivakano, to be charged.
