Binny recalled that Kejriwal had organised a referendum across Delhi before forming the government.
"Kejriwal should have held a referendum to take a decision on me. He should have organised a public meeting in my constituency (Laxmi Nagar) before arriving at any conclusion. After becoming Chief Minister of Delhi, he has become a dictator and is taking all decision on his own," he told reporters at Jantar Mantar.
The MLA said he would continue to raise public-related issues even if it amounted to indiscipline.
"He (Kejriwal) recently sent a letter ...stating that disciplinary action was being taken against me," Binny said, adding that if raising public-related issues is violation of discipline, he would continue doing so.
Instead of taking action against me, Kejriwal should have taken action against Law Minister Somnath Bharti who allegedly assaulted and misbehaved with African women during a midnight raid.
Asking how many days he would sit on dharna at Jantar Mantar, the MLA said that he would soon apprise the media about his strategy.
Binny was expelled from the party last night following a decision by the AAP's disciplinary committee.
"This disciplinary committee has decided to expel Vinod Kumar Binny and terminate his primary membership from the party, for publicly making false statements against the party and its leadership, thereby bringing disrepute to the party," the party had said in a statement.
Ten days ago Binny had called Kejriwal a "dictator" and accused the party of "betraying" the people of Delhi by backtracking on its election promises.
Binny had announced that he will sit on a dharna at Jantar Mantar if the party fails to fulfil the promises made to people by January 2.
