Entrepreneur Development Minister Mohd Redzuan Yusof has rebuffed calls for him not to touch on the Lynas waste issue which does not fall under his ministry, stating that those who asked for him to do so needed to be "schooled".

"Asking me to zip my mouth and focus on my own ministry - I think they need to be schooled.

"As a cabinet minister, I have a locus standi to speak about Lynas... I was voicing the cabinet consensus. It is (Deputy Minister in the Prime Minister's Department) Fuziah (Salleh) who does not have a locus standi.

"As for Energy, Science, Technology, Environment and Climate Change (Mestecc) Minister Yeo Bee Yin, her ministry would often have overlaps, so she shouldn't work in a silo.

"She should work in a team," he told Utusan Malaysia.

Last Saturday, Redzuan said Lynas can continue to operate its rare-earth processing plant in Gebeng, Kuantan, stressing the importance of foreign direct investment.

Redzuan later also claimed Yeo's decision requiring Lynas to send its radioactive Water Leach Purification (WLP) residue out of the country, was not endorsed by the cabinet.

Fuziah, who is also Kuantan MP, subsequently asked Redzuan to stop commenting on the issue, stating that he had no locus standi.

Bentong MP Wong Tack, who led protests against Lynas, had also made similar calls.

Redzuan was quoted as saying that some ministers did not get accurate information on Lynas and had politicised the issue for political support.

"Be honest, to government MPs, change your 61-year attitude as the opposition," he was quoted as saying.
