President Ferdinand Marcos Jr. should start cracking his whip on non-performing members of his Cabinet, Senate President Juan Miguel "Migz" Zubiri said Wednesday.

"My suggestion to the president is to crack the whip on his Cabinet, especially the poorly performing members of the Cabinet that are causing him headaches," Zubiri told reporters in a press briefing at the Senate when asked about the dwindled approval rating of the President in the third quarter of the year.

In a survey released by the polling firm Pulse Asia, the approval rate of Marcos dropped from 84 percent in June to 65 percent in September.

According to Zubiri, what transpired in the last month should be dissected to fully understand the reason for the decreasing approval rate of the president.

"The number one problem being faced by our fellow Filipinos is the inflation or the rising prices of commodities and basic services," he said.

"I mean, if the problem is inflation, then look at the agencies that are supposed to trace and track why there is an overpricing for example," he added.

He continued: "Why is there a hoarding? Why is it no one is being arrested for hoarding? Why are price manipulators on the market's side still not being called out?"

These are the questions, the Senate chief said, that the President can ask his Cabinet.

"If they're not performing up to par with the President's standards, I think they should be replaced, with due respect, without naming names," he said.

Zubiri said he is thinking of at least three to four Cabinet members who are not performing well.
