PKR's candidate for the Sungai Kandis by-election Zawawi Mughni has denied lobbying to be nominated.

"I have never lobbied. (But) my friends did propose me to the relevant people," Zawawi told reporters when met in Sungai Kandis today.

Asked if there was any dissatisfaction over him being picked for the Selangor state seat, the tahfiz school headmaster said this was normal in politics.

"But after a final meeting yesterday, they (other potential candidates) supported me, because whoever was chosen they would support," he said.

Numerous names had floated about prior to PKR president Dr Wan Azizah Wan Ismail naming Zawawi last night.

At a press conference earlier, Selangor Menteri Besar Amirudin Shari denied putting forth any names.

"All I did was attend state and central politic bureau meetings and voiced my opinions," he said.

He also said that the decision announced by Wan Azizah was final.

Speaking to reporters after the launching of the party election machinery last night, Zawawi, 47, said he was grateful for the trust placed on him by Wan Azizah and vowed to carry on the work began by the late Sungai Kandis assemblyperson Mat Shuhaimi Shafiei, whose death after battling lymphoma earlier this month triggered the by-election.

"There are many areas in the villages in need of overseeing, (issues) such as clogged drains, rubbish disposal and streetlights in need of upgrades.

"We shall continue what has been done by Mat Shuhaimi. I was able to work with him before (his death) and I am confident the voters of Sungai Kandis are in need of support from a leader, for a better life," he said last night after at the launching of the party election machinery.

Nomination for the Sungai Kandis by-election will be held tomorrow.

It is expected to be a straight fight between PKR and Umno.

The by-election has been set for Aug 4.

On May 9, PKR's Mat Shuhaimi obtained 23,998 votes to win the Malay-majority seat, defeating BN's Kamaruzzaman Johar (11,518), PAS' Mohd Yusof Abdullah (7,573) and PRM's Hanafiah Husin (76).
