Bangladesh Bank on Tuesday asked the scheduled banks to keep open their branches located in Dhaka and Chittagong cities on Friday and Saturday to facilitate the filing of nominations for the upcoming city corporation elections in the areas. The central bank issued a circular to managing directors and chief executive officers of all banks asking them to keep open their all branches in the two cities on March 27 and 28 as the candidates of the city polls will have to submit their deposit money by March 29 through pay-order or treasury invoice to the Election Commission along with their nomination papers. Banks in the country usually remain closed on Fridays and Saturdays. The last date for filing nominations is March 29. The Election Commission earlier announced that the election of the three city corporations, Dhaka north and south and Chittagong, will be held on April 28.
