The outgoing Tongan MP 'Isleli Pulu blames his election loss on his decision to leave the Democratic Party's candidate list.
Mr Pulu stepped down in protest at how the list was chosen, and openly disagreed with Party leader Akilisi Pohiva.
Mr Pulu was beaten comprehensively by a former journalist, Mateni Tapueluelu, who was backed by the party in the Tongatapu 4 constituency.
Mr Pulu, who has been in parliament for 14 years, says he holds some regrets.
"To some extent yes, I feel. But I've totally forgot it now because I'm already out. This should give Akilisi a chance and the rest of the team to prove to the government and also the people of Tonga they are capable."
Mr Pulu says he will still support the democratic movement.
