Tonga's Prime Minister's office has confirmed the ousted Thai prime minister, Thaksin Shinawatra, has been in the country this week.
A government spokesman in Nuku'alofa says his visit was privately arranged and included no meetings with officials.
Earlier this week Thaksin was in Fiji, whose interim government has confirmed the visit but declined to reveal the nature of the discussions with the interim prime minister, Commodore Frank Bainimarama.
The former Thai politician, whose Thai passport has been cancelled, is wanted in Bangkok to answer corruption charges.
Commodore Bainimarama seized power in a coup, purportedly to stop corruption.
On his way to Fiji, he narrowly escaped arrest in Malaysia during a refuelling stop of his private jet.
