From the prime minister's claims of waging a war against corruption to his trips abroad to attract investments, the former PKR leader and MACC chief says the government has failed the people.

Zaid Ibrahim says the post of political secretary is a demotion for Shamsul Iskandar Md Akin, whose sacrifice ensured that Anwar Ibrahim could realise his prime ministerial ambitions.

Shamsul Iskandar Md Akin's account of how he was prevented by his party chief from contesting his narrow defeat to Umno president Ahmad Zahid Hamidi seems to hit a raw nerve in the Umno leadership.

It comes after the prime minister was grilled by a US-based network on the decision to drop 47 charges against his deputy.

A proposal to revert to the previous system, which limits voting rights to just 2,500 delegates, has raised concerns about money politics.

Umno leaders want answers to why the party chief did not report the Agong's demand earlier.

The Umno president's stranglehold on his party has been a rock for the prime minister over the past year.

Questions are raised about the sentencing of Muar MP Syed Saddiq Syed Abdul Rahman.

For his part, the deputy prime minister says he is ready to shoulder any responsibility given to him.

The former leader pens a sarcastic post on the 'unique' case.

It says opposition MPs 'are being subjected to interrogations, investigations and politically motivated criminal prosecutions'.

Former prime minister Muhyiddin Yassin is also questioned on his remarks during the Simpang Jeram by-election campaign in Johor.
