The parliamentary seats were left by those who became government leaders or officials in the 2015 general election, U Aung Myint told the press after a meeting of the House of Nationalities (Upper House) in Nay Pyi Taw on August 22. 

The number of vacant seats will be confirmed when time approaches, he said, without giving a specific date. 

Myanmar held a general election to elect parliament representatives in November 2015, in which the National League for Democracy (NLD) won the absolute majority of seats in the two houses.
