Mired in controversy, the 10th parliamentary elections are being held in just 147 out of 300 seats in 59 out of 64 districts of the country. As many as 153 candidates have already been elected unopposed amid a boycott by the main opposition party and its allies.
More than half of the country’s 100 million voters are not getting an opportunity to vote in the elections that have already sealed a victory for Prime Minister Sheikh Hasina after the opposition boycotted the contest.
Some 21 parties, including former prime minister Khaleda Zia’s Bangladesh Nationalist Party (BNP) are boycotting the elections over Hasina’s refusal to introduce a non-party interim government to oversee the election.
The BNP Friday announced another shutdown for 48 hours starting Saturday. The shutdown, aimed at protesting the confinement of Zia and to seek cancellation of the polls, will end at 6 a.m. Monday.
Since Nov 26, the opposition alliance has enforced nationwide blockade for 22 days in phases, demanding that the elections be scrapped and fresh polls held under a caretaker government.
