Three Malay majority state seats held by PKR in Penang appears to be high priority for Umno, as this area saw the largest increase in new voters, claimed Chief Minister Lim Guan Eng.

Lim said the state seats were Batu Maung, Sungai Bakap and Penanti, held by Abdul Malik Kassim, Maktar Shapie and Norlela Ariffin respectively.

"The worst is Batu Maung which has seen an increase of 7,000 voters, followed by Sungai Bakap, 4,000 voters and Penanti," Lim told reporters in Penang today.

Describing the three seats as part of Umno's "hit list", Lim said he was not sure how many new voters are there in Penanti, but the overall situation was "shocking and disturbing".
