Myanmar (Burma) had been under military rule since 1962 when General Ne Win staged a coup against the democratically elected government of U Nu.
Rance's prompt action in making U Nu prime minister within hours is believed to have been a decisive factor in avoiding greater upheaval.
"The military has dominated government since General Ne Win led a coup in 1962 that toppled the civilian government of U Nu. Burma remains under the tight control of the military-led State Peace and Development Council."
U Nu, the first Prime Minister of Independent Burma, appointed U Tin Tut to be his Minister of Foreign Affairs.
The new Democratic Party, established by Mya Than Than Nu, the daughter of former Prime Minister of Burma, U Nu and Nay Ye Ba Swe, the daughter of former Prime Minister Ba Swe, is aiming to take part in the election.
