Awami League general secretary Obaidul Quader left for Singapore on Friday morning for a routine health check-up.
Awami League office secretary Biplob Barua said that Quader, also Road Transport and Bridges Minister, left Dhaka on a Biman Bangladesh Airlines flight around 8.30am.
"He has gone for a routine health check-up at Mount Elizabeth Hospital. For a long time, he was unable to travel to Singapore for a follow-up checkup due to the Covid outbreak. He will return soon," said Biplob.
The 69-year-old AL leader has been suffering from chronic heart and lung problems for a long time. In 2019, three blockages were found in his coronary arteries.
