Oct 1, 2008 (DVB), Dr Myo Win, elected member of parliament for Kawa township, Bago division, died of liver cancer on Monday at Phawat private hospital in Mae Sot, Thailand, his wife said.
Dr Myo Win's wife Nilar Aung said his liver problems had begun in April, but there was a delay in receiving treatment because the couple did not have national identity cards.
He went to Bangkok and Chiang Mai for tests and treatment but died on Monday afternoon. He was 54.
His body is to be cremated on 3 October in Mae Sot, Nilar Aung said.
Daw San San, vice-chair of the Members of Parliament Union and a Seikkan township MP said Dr Myo Win's death was a great loss to the ongoing struggle for democracy.
"We have ongoing issues with the United Nations credentials committee and there are other matters that he was involved in," she said.
"It is like breaking an oar while rowing. He was not that old."
The son of U Cho and Daw Tin Nyunt, Dr Myo Win graduated from No. 3 Basic Education High School in Bago and went to on to study at Mandalay medical university, gaining his medical degree in 1981.
He took part in the 1988 uprising and became the chairman of Kawa township National League for Democracy and won his seat in the 1990 election with 67.65 percent of the vote.
He was detained from 1998 to 2001 by military intelligence and fled to the Thai border in 2004.
He is survived by his wife Nilar Aung and their three children.
