Mohd Hamdan, 60, had been an elected representative of Permatang Pasir for three terms since 1999. He was also a former state PAS chief for 14 years.
Mohd Hamdan’s body is expected to arrive in Permatang Pasir by 2pm today and will be buried at the Permatang Pasir Muslim cemetery after the Asar prayer.
The Election Commission will now have to call for another by-election within 60 days - the eighth by-election since March 2008 general election - now that the seat has been left vacant with Mohd Hamdan's death.
Permatang Pasir is one of three state seats in Permatang Pauh - the parliamentary constituency held by PKR de facto leader, Datuk Seri Anwar Ibrahim. It is the sole PAS seat in Penang.
The upcoming by-election will be the third by-election in the Permatang Puah constituency in less than one year - the first being Datuk Seri Anwar's victory in August last year after his wife, PKR president Dr Wan Azizah Wan Ismail, quit the seat.
The other state seat in Permatang Puah, Seberang Jaya, is held by Arif Shah Omar Shah from Umno - the man who was defeated by Datuk Seri Anwar in the by-election for the parliamentary seat.In KOTA BARU, PAS spiritual leader Datuk Nik Abdul Aziz Nik Mat said the party would contest in the by-election for the Permatang Pasir state seat, which he said was a PAS stronghold.
In the last general election Mohd Hamdan, who bagged 11,004 votes, defeated Ahmad Sahar Shuib from Umno (5,571) by a majority of 5,433 votes.
