PUTRAJAYA, May 16 — Former Attorney-General Tan Sri Abdul Gani Patail claimed he had prepared charges against Datuk Seri Najib Razak before he was abruptly removed, according to Tun Dr Mahathir Mohamad.

Gani had been leading a special task force to investigate the 1Malaysia Development Bhd (1MDB) scandal prior to his enforced departure, which the government then purported to be due to his failing health.

"I met with him yesterday to learn what happened when he was removed and what was the result of his investigations,” Dr Mahathir recounted from their meeting yesterday at the Perdana Leadership Foundation here.

"He claimed he was preparing to charge Najib and that morning, he was deprived of his position,” Dr Mahathir told reporters today.

Dr Mahathir yesterday met with several senior officials at his office here, including Chief Justice Tun Md Raus Sharif, Inspector-General of Police Tan Sri Mohamad Fuzi Harun and former Special Branch deputy director Datuk Abdul Hamid Bador.

Abdul Gani called time on his tenure as AG in July 2015, and was replaced by former Federal Court judge Tan Sri Mohamed Apandi Ali.

There have been calls for Raus to step down as CJ due to allegations that his appointment had violated the Federal Constitution.
