There is still time for Sarawak PKR and its DAP counterpart to negotiate the clashes in six seats in the state election, jailed former opposition leader Anwar Ibrahim said.

He urged the two parties to discuss the matter to ensure the victory of Pakatan Harapan in seats they are contesting.

"I regret (that this happened in Sarawak state election)," he said when met at the High Court in Kuala Lumpur today.

"For now, I want them to continue to work to ensure that Harapan wins," he said upon arrival at the court complex.

"There is still time for them to try to negotiate, that will be the best," he added when asked about the clashes of the state PKR and DAP in six seats.

Both Sarawak PKR and Sarawak DAP are engaged in multi-cornered fights in the state seats of Mulu, Murum, Simanggang, Mambong, Ngemah and Batu Kitang.

Anwar arrived at the Duta Court Complex to seek leave from the High Court to refer to the Federal Court the issue of whether the Pardons Board’s refusal to pardon him on his sodomy conviction can be challenged.

In his negotiation with DAP secretary-general Lim Guan Eng, PKR deputy president Azmin Ali had agreed in principle to surrender eight state seats, including the five contentious ones, to PKR on April 7.

The five seats are Mulu, Murum, Simanggang, Mambong and Ngemah.

On April 11, Pakatan Harapan announced that the allies had arrived at a consensus on seat negotiation.

The decision, however, did not go down well with Sarawak PKR, which vetoed the national decision.

Azmin, however, authorised the state chief Baru Bian to issue letters to the candidates to contest in the five seats.

In his explanation, he said he has obtained the written mandate of party president Dr Wan Azizah Wan Ismail for him to deal with outstanding issues related to the state polls, including the seats and candidates.

Azmin deemed that the seat negotiation has not been concluded as Harapan did not reveal details related to the seats.

In retaliation, Sarawak DAP fielded its candidate Abdul Aziz Isa in Batu Kitang.
