It’s time for Datuk Seri Najib Razak to reveal the truth about the scandals and issues surrounding his administration, said UMNO veteran Tengku Razaleigh Hamzah.

The Gua Musang MP, popularly known as Ku Li, said Tun Dr Mahathir Mohamad must have had a good reason to have criticised the Prime Minister so harshly in his latest blog entry, The Malaysian Insider reported.

"He (Dr Mahathir) wants to know the truth behind this.

"It is high time that real answers are given, that the truth comes out of these things," the news portal quoted Ku Li as saying at Parliament lobby today.

He added that, as an experienced leader, Dr Mahathir knows how things are in political organisations facing the general election.

"It is going to be very difficult for anyone to get support if there are still unresolved issues," Ku Li reportedly said.
