Umno information chief Annuar Musa refused to reveal how he came to the conclusion that Bersih chairperson Maria Chin Abdullah has links with the US Central Intelligence Agency (CIA).

"I don't need to reveal that information, even if I have it," he told Malaysiakini.

Yesterday, Annuar claimed that Maria and her late husband Yunus Lebai Ali had CIA links through their work with various election monitoring groups.
