Kelantan's Melor assemblyperson Md Yusnan Yusuf passed away at 2.28am this morning at his home in the constituency.
The 53-year-old PAS representative's passing was confirmed by his son Mohd Auzaie on Facebook.
Mohd Auzaie told Bernama that the death was due to a heart attack and that Yusnan had been suffering from heart disease since 2016.
Mohd Auzaie said his father would be laid to rest this afternoon.
In a separate Facebook post, Kelantan Menteri Besar Ahmad Yakob extended condolences to the family on behalf of the state government and state PAS chapter.
Md Yusnan was Kelantan's deputy executive councillor in charge of Islamic development.
He first won his Melor state seat in 2013.
"The deceased was a former assistant professor at the International Islamic University Malaysia, and had served as an education expert for the Islamic Educational, Scientific and Cultural Organization (Isesco) in Rabat, Morocco," Ahmad said.
At present all elections have been suspended due to the state of emergency.
