The BNP has deferred tomorrow's rally at Suhrawardy Udyan to November 11 due to the ongoing 63rd CPA conference.
On November 7, 1975, Ziaur Rahman, then chief of army staff, was freed from captivity in Dhaka cantonment, paving the way for Zia to come to power.
The BNP has chalked out a 10-day programme to observe the day with various programmes.
The party also has a plan to hold a rally at Suhrawardy Udyan on Saturday to mark the day.
BNP chairperson Khaleda Zia and secretary general Mirza Fakhrul Islam Alam in separate messages greeted the country's people on the occasion.
While the BNP and its alliances celebrate November 7 as the National Revolution and Solidarity Day, the ruling Awami League and its front organisations consider it as the day of “killing of freedom fighters”.
