Okonoboh was impeached on Monday at the Assembly in Benin City, the state capital.
Okonoboh was impeached at the House of Assembly in Benin City, the state capital, after a letter of a vote of no confidence was read at plenary. The impeachment notice was signed by 16 members of the 24-member Assembly.
Honourable Kabiru Adjoto has been elected as the new Speaker. He becomes the fourth Speaker of the current Assembly that was inaugurated in 2015.
Okonoboh was impeached for what has been described as an abuse of the power vested in his office.
While speaking on Monday, new Speaker, Adjoto, said, "We discovered that for selfish reasons, the ex-Speaker would adjourn the House, possibly, because the wife is doing a birthday or the son is having a graduation at Covenant University or the son is going to an NYSC camp and he wants to do a party for him.
"Between June and July, we have worked for just three weeks; he adjourned the House for more than six weeks.
"Today is August 15, we are just resuming. Then, the House is expected to adjourn again next week for another four weeks for the normal holiday. Is that a normal parliament?
"All of us came together and said, 'Enough is enough.' The institution is more deserving to be protected that the interest of an individual.
"The ex-Speaker’s wife, like I said earlier, has turned herself into the 25th member of the House of Assembly to the extent that anything we discussed in the executive session, the wife will hear and start calling our wives to tell them what was discussed.
"The wife uses the convoy as if she is Mr. Speaker and at random. The other day, the wife and the son used the convoy to the NYSC camp. When the soldiers and policemen there saw that it was coming, they all stood, hoping that they would see Mr. Speaker, only to see the wife and the son to come out of the vehicle. That is a desecration of the Parliament."
Victor Edoro, who was also removed as Speaker for alleged misconduct in May 2016, was elected the new Deputy Speaker of the House to replace Honourable Elizabeth Ativie.
Roland Asoro also became the new Majority Leader of the House on Monday.
Okonoboh, Ativie and former Majority Leader, Foly Ogedengbe were all suspended for three months by the new leadership of the House.
A three-man panel was also set up to probe the impeached Speaker's tenure.
