Former PKR vice-president Rafizi Ramli today provided his detractors – including his colleagues in Pakatan Harapan – with reasons why he will continue to be critical of the government.

Taking to Twitter, Rafizi explained that voicing out on particular issues is vital to keep the government in check.

"I read comments telling me off: 'You are in government now.' 'Don't be sour grapes. Why must you run down the Harapan government? What have you done to help the country/ Harapan government?

"There are strong reasons why we must continuously speak up: 1) need to regain the narrative on social media 2) check and balance is good," he said.

Rafizi had come under fire earlier today from Entrepreneur Development Minister Mohd Redzuan Md Yusof for being critical of the Harapan administration. 

“Rafizi is a smart person, but he should help Harapan govern the nation for the better, instead of running us down,” he said.

Redzuan was responding to an opinion piece penned by Rafizi, in which the latter said that Harapan should focus on delivering its election promises rather than being sidetracked by "internal power dynamics."

He also stressed that it would be futile for Harapan – which obtained less than 30 percent of Malay votes in the May general election – to outdo Umno and PAS in the hope of winning the support of the community. 

Yesterday, Rafizi penned an open letter to Finance Minister Lim Guan Eng to urge Putrajaya to return to the weekly managed float system for fuel – as had been practised under the BN administration – given the falling price of crude oil.

Rafizi said, by using a weekly formula, the price for RON95 would have seen a 20-sen drop in the coming weeks.

This came after Lim said Putrajaya used the monthly average price of Brent crude to determine how much it has to subsidise to maintain the ceiling price of RM2.20 per litre for RON95.
