It was announced on July 22 that the duties and responsibilities of Pro Tem President related to the National Defence and Security Council’s affairs had been assigned to the Chairman of the State Administration Council.

It has already announced that Pro Tem President U Myint Swe is on medical leave and receiving medical treatment. In such situation, in order to carry out the National Defence and Security Council's affairs, the Pro Tem President Office sent a letter to the SAC  Office saying that the responsibilities of Pro Tem President will be handed over to SAC Chairman while Pro Tem President U Myint Swe cannot serve the council's duties as he is on medical leave.

The duties of Pro Tem President for National Defence and Security Council's affairs were transferred to the State Administration Council Chairman through a signing event at 11:30 on 22 July 2024.

Pro Tem President U Myint Swe has been receiving regular medical treatment provided by a medical team comprising specialists as he has been suffering from psychomotor retardation and malnutrition since early 2023 according to SAC  Information Team.

According to the medical examinations, he is suffering from neurological disorders and peripheral neuropathy disease. Hence, he received a neurological medical checkup at Mount Elizabeth Medical Centre in Singapore from 15 to 19 April 2024 and further medical treatments at No 2 Defence Services General Hospital (1,000-bed) from 27 May to 18 June 2024.

During the period, Pro Tem President U Myint Swe also received surgical treatment for cataracts in his right and left eyes and improved his eye sight. But, he is still suffering from peripheral neuropathy disease. As such, he is now receiving close medical treatments from a special medical team at his home after taking a medical leave from 18 June to 30 July. An eight-member special medical team led by Union Minister for Health Professor Dr Thet Khaing Win performed a medical checkup on the Pro Tem President on 30 June and 14 July.

In this regard, his health condition has not improved yet. As he cannot do normal daily activities including eating food, and therefore, close medical treatments are being provided for the Pro Tem President under the arrangement of the SAC.
