Yangon - Opposition parties urged the government Monday not to change the electoral system next year, saying it is not yet the right time to use a proposed proportional representative system.
Leaders of the National League for Democracy (NLD) and four main ethnic political parties met Sunday to discuss the parliament's decision to implement the change for the 2015 general election.
"We got agreement with ethnic parties to protest against changing electoral system," NLD spokesman Nyan Win said.
"This only makes confusion for voters and we believe this PR system is no good for country at this time," he said.
An alliance of 20 ethnic parties also announced in late June that they would not accept the proposed changes.
Parliament approved a bill last month to adopt the new system proportional representation system for the upper house in 2015. Under the current system, the winning candidate in each constituency gets a seat in parliament.
Proportional representation would apportion legislative seats to each party based on the total number of votes received in the general election. The government argued that the change would provide more opportunities for smaller parties.
