Dhaka, Jan 5 (ANI): Bangladesh is today marking the first anniversary of the controversial 2014 prime ministerial elections that was boycotted by the BNP-led coalition. Earlier on Sunday, police besieged former Bangladesh Prime Minister and chief of Bangladesh Nationalist Party (BNP), Khaleda Zia, at her office, amid fears of violence as the opposition party planned rallies across the country. The BNP and its allies had boycotted the election that was held in January 05, 2014 which was marred by deadly unrest. Bangladesh Prime Minister Sheikh Hasina held to her stance that a fresh poll can be called only if her rivals halt violence. The BNP denounced Hasina's scrapping of the practice of having a caretaker government oversee elections. On Sunday, the BNP party workers held a protest in front of the party office to know the reason as to why the police besieged the party chief.
