The Sammilita-Forum panel led by Rubana won all the 35 posts of directors in the elections held on Saturday.
Jahangir Alamin of the election board announced the results after voting was held from 8am to 4pm in Dhaka and Chattogram.
Rubana, the wife of late Dhaka North mayor and former BGMEA president Annisul Huq, won 1,280 votes.
Out of the 1,956 voters, as many as 1,492 cast their ballots, according to election board member Nihad Kabir.
The 35 directors – 26 from Dhaka and nine from Chattogram - will now elect the president and seven vice presidents in line with the rules.
But in the last few elections, leaders have been elected through a compromise between the two councils.
The emergence of the Swadhinata Parishad this time forced the two panels to join forces and announce the combined council headed by Rubana.
