Political hopeful Clive Palmer has demanded a new election in the Sunshine Coast seat of Fairfax after accusing the Australian Electoral Commission of tampering with votes.

The mining magnate turned politician says he's sought a court injunction to uphold the integrity of the counting process while his gripe is being looked at.
