It was learnt that the lawmakers have signed the impeachment notice against the deputy governor.
This emerged following an emergency plenary session summoned by the assembly leadership and the presence of heavy security operatives at the Assembly gate.
It was alleged that Aiyedatiwa while he was the acting governor, following the medical vacation of the governor, Rotimi Akeredolu, he reportedly approved N300m for the purchase of a bulletproof SUV for his personal use.
Recall that the governor travelled to Germany for medical treatment for three months.
Aiyedatiwa was alleged to have ordered the N300m to be sourced from the palliative fund, which was from the Federal Government to the state to cushion the effect of the removal of fuel subsidy.
Akeredolu had on return from medical vacation sacked all the media aides attached to the deputy governor over alleged insubordination.
It was reported that rumours of the underground plot to impeach the deputy governor were rife after the sack of his aides by the governor.
However, this development was coming days after the Speaker of the state House of Assembly, Olamide Oladiji, dismissed that there was a plot to impeach the deputy governor.
Corroborating the Speaker, the Majority Leader of the Assembly, Mr Oluwole Ogunmolasuyi, said the rumour should be ignored.
“Nobody is plotting any move to impeach the deputy governor. We are busy with what will bring development to the state. What is of importance to us is to carry out our duties,” he said.
Also denying the plot earlier, the deputy governor, Aiyedatiwa, in a statement denied a purported pre-signed resignation letter said to be circulating in the public domain.
Chairman of the House Committee on Information, Olatunji Emmanuel, could not be reached for comment as the plenary was still on as of the time of filling in the report.
Also, government officials kept mum on the development in the assembly.
