The federal government has ordered the Inspector General of Police, Mohammed Adamu, to provide security for the 17 Edo All Progressives Congress (APC) lawmakers.
Minister of Justice and Attorney General of the Federation, Abubakar Malami, gave the order in a letter.
It followed a petition to his office by Idahosa-West Chambers.
Malami explained that the directive became necessary to prevent breakdown of law and order.
The APC legislators are loyal to former national chairman, Adams Oshiomhole, and the governorship candidate, Osagie Ize-Iyamu.
On Thursday, they clashed with lawmakers loyal to Governor Godwin Obaseki.
Obaseki has vowed to deal with perpetrators of violence.
He indicted Oshiomhole, his predecessor, for the Edo Assembly change of leadership and turmoil in the state.
Meanwhile, Governors elected on the platform of the Peoples Democratic Party (PDP) have condemned Thursday’s police invasion of the Edo state House of Assembly.
Describing the invasion as illegal, the governors said the action was meant to give cover to the unlawful and unconstitutional acts allegedly hatched by some “former members-elect” of the Assembly.
The governors, in a statement issued on Friday under the aegis of the PDP Governors Forum, also condemned the swearing-in of some members-elect and the subsequent election of new presiding officers in a private residence without the legitimate Assembly officials as required by law.
