ATM Kamal was expelled on June 4.

Protesting the decision, Hasan said the expulsion is unlawful as it was not done as per the provisions of the party constitution and not discussed even at the national executive committee.

"The expulsion was a unilateral and autocratic decision taken by the president, executive president and secretary general without any regard to democratic norms," he said.

The charge against Kamal is based on the facts that he had the audacity to raise his voice in favour of reforms and against certain corrupt militants who have joined the LDP, Hasan claimed.

" Kamal, I believe, was singled out and targeted so that other vocal pro-reformist leaders in the party are silenced," he alleged.

Hasan urged party president, executive president and secretary general to refrain from, what he said, undemocratic behaviour and indulgence in corrupt practices, instead of fulfilling the promises they made in the past two years.
