There have been allegations of nobles attempting to bribe members of the Democratic Party to join forces with them.
Speaking to the Tongan programme Le'o 'o e 'Otu Felenite, 'Akilisi Pohiva says as far as he's concerned, his democratic party is united and no one has buckled under any of the bribes.
He says if re-elected, he's determined to eliminate corruption in government so that they're able to move forward as a nation.
Pohiva says corruption is hindering Tonga's progress and although he cannot get rid of it, they'll definitely try to reduce it.
