Police however barred the procession when it reached Bijoy Nagar intersection.

Earlier, the CPB held a rally in Muktangan in the capital before marching towards the EC.

"Black money holders indiscriminately use their power to be MPs as it's now the most profitable business in the country," CPB General Secretary Mujahidul Islam Selim told the rally.

Even the major political parties are interested in giving nomination to those who have huge black money and influence, he said.

"Black money holders can't be elected MPs if a proportional electoral system were introduced," he added.

On reforms in caretaker government system, he said it should be done by consensus among all the political parties. The main opposition Awami League has not yet cleared its stance on the reforms, he added.

He put emphasis on checking the use of muscle power and black money in the elections.

CPB leaders Ahsan Habib Lablu, Ruhin Hossain Prince and Mahbub Alam, among others, addressed the rally.
