He said Moudud was admitted to the Mount Elizabeth Hospital around 6:30am on Tuesday and he has been receiving treatment under cardiologist Charles Toh.

Sujon said Moudud will initially undergo some medical tests for his anaemia, heart and some other problems. “Doctors at the Singapore hospital will also examine whether the permanent pacemaker implanted in his heart is working properly.”

He said Moudud urged all to pray for his speedy recovery.

On December 30, Moudud, in his 80s, was admitted to Evercare Hospital in the capital as he had fallen ill due to low level of haemoglobin. He also suffered a mild stroke while undergoing treatment at the hospital.

Later on January 7, a permanent pacemaker was implanted in the heart of the ailing BNP leader.

A pacemaker is a small, battery-operated device which senses when one's heart is beating irregularly or too slowly. It sends a signal to one's heart that makes one's heart beat at the correct pace.

Moudud Ahmed was one of the founding members of the BNP when it was formed in 1978 by Ziaur Rahman.  He joined Jatiya Party in 1985 and served as the Prime Minister and Vice President in military ruler HM Ershad’s government.

His wife, Hasna Moudud, is the daughter of famous poet Jasimuddin.
