Negeri Sembilan Menteri Besar Aminuddin Harun has dismissed as "mischievous speculation" talk that Rafizi Ramli will contest in a by-election for the state seat of Rantau and replace him in the state's top post.

Utusan Malaysia quoted Aminuddin as saying that Rafizi, the incumbent PKR vice-president, had a "bigger role to play," instead of being confined to a state.

"There is yet to be a court ruling on the Rantau by-election, and there is so much speculation. It's not that I love my position too much. I will give it up if the (PKR) leadership wants it.

"It's just that I feel that talk of Rafizi being appointed as the Negeri Sembilan menteri besar is mischievous, because he is to have a bigger role, and not just lead a state," he told a press conference after chairing a state executive council meeting in Seremban today.

Aminuddin was responding to rumours that Rafizi will be named as Pakatan Harapan's candidate should the court decide a by-election be held in Rantau.

The PKR candidate in the 14th general election, Dr S Streram, had filed an election petition to challenge the result for the state seat.

Rantau was won uncontested by BN candidate Mohamad Hasan, the former Negeri Sembilan menteri besar and current Umno deputy president, because Streram was barred from entering the nomination centre on nomination day.

Should a by-election be called, Aminuddin said he had two or three suitable candidates in mind, who are also locals.

However, the final decision will be made by the PKR leadership, he stressed.

Aminuddin only recently returned to work after undergoing bypass surgery on Oct 29.
