Clive Palmer has filed a claim in the Supreme Court seeking more than $1 billion in damages from FTI Consulting, the former administrator of his Queensland Nickel business, the ABC reports.

FTI has previously indicated it would fight any legal action and this afternoon a spokesman declined to comment on the matter.
