Jailed ex-deputy premier Anwar Ibrahim has filed a notice to appeal to the Federal Court against the appellate court's decision today to uphold the sodomy conviction and nine year-jail sentence meted out to him.

His lawyer Sankara Nair said he had filed the notice at the Court of Appeal registry this afternoon so that the matter could be brought up at the highest court in the land.

"Like us, our client is not satisfied with today's decision which he described as a 'travesty'.

"Although he is doubtful of getting a positive outcome (at the Federal Court), he has instructed us to file the notice of appeal," he said.
