DAP has sought an explanation from its Malim Nawar assemblyperson Leong Cheok Keng (above) following reports about his alleged move to join MCA.

Nanyang Siang Pau reported yesterday that Leong had applied to join MCA while DAP's Pokok Assam representative Leow Thye Yih was on the cusp of quitting the party.

Leong has yet to publicly comment on the speculation while Leow has denied it.

Speaking to Malaysiakini, DAP disciplinary committee chairperson Chong Chien Jen said Leong had three days to explain himself.

Failing which, disciplinary action would be taken.

"We asked him to explain if the Nanyang report is true. We can't just make decisions based on a media report," he added.

Leong has yet to respond to repeated requests for comment.

Meanwhile, MCA deputy president Mah Hang Soon neither confirmed nor denied the news.

He merely told Malaysiakini that the party welcomed anyone who had similar ideas and goals.

In a separate statement today, Chong said DAP has issued Leong a show-cause letter.

"Any act of applying for membership to another party is deemed treacherous to our party," he added.

In the last general election, Leong defended the Perak state seat with a resounding 6,082 majority despite a three-cornered fight against MCA and PSM. He is a two-term assemblyperson.

Over the past two years, Leong has been at odds with Perak DAP chairperson Nga Kor Ming.

When Tronoh assemblyperson Paul Yong was accused and later charged with raping his domestic worker, Leong lambasted Nga for his position on the case.

The Perak DAP deputy treasurer quit the party in September 2019, only to backtrack on his decision two months later.

Leong again criticised Nga when DAP momentarily considered working with Umno last December to form the new Perak state government.
