There has been growing dissatisfaction with how the once-dominant Malay party is being treated by its ally.

MCA and MIC leaders have gone against a call by senior Umno leaders who say Pakatan Harapan's candidate should be regarded as their own.

Some recall criticism by Pakatan Harapan politicians of the previous government's move to send text messages on behalf of the National Security Council.

The deputy prime minister says Umno agreed to the pact as long as it covered matters such as the defence of Islam and the special rights of the Malays.

MPs from Barisan Nasional appeared to stay out of the fray over the use of the term 'unity government'.

Fadillah Yusof says the signing ceremony will be held tomorrow.

The PN chairman says the 'decree' for a unity government was actually a suggestion or view put forth by the ruler.

A voice identical to that of the Umno Supreme Council member is also heard warning DAP that the government could collapse 'if they talk too much'.

Many who had openly rejected cooperation with Pakatan Harapan now appear to have made tacit U-turns.

He says Perikatan Nasional prefers to act as a check and balance in Parliament.

Mohd Asri Zainul Abidin says that with strong support, the new government will not need to worry about threats by certain groups to leave if their demands are not met.

He says the matter will be discussed with the component parties of the unity government.
