Senator Francis Alimikhena has led several All Progressives Congress (APC) to the Peoples Democratic Party (PDP).
The lawmaker represents the Edo North senatorial district in the National Assembly.
In May, Alimikhena dumped the APC for the PDP where he won the 2023 ticket.
He will face ex-APC national chairman Adams Oshiomhole who emerged as the party’s Edo North flagbearer.
On Friday, the defectors explained that they left the APC to join the senator because of “injustice”.
They said the party denied Alimikhena the return ticket in favour of the former governor.
Deputy governor Philip Shaibu said he was elated to reunite with those he had shared political journeys with in the past.
“You’re welcome to the PDP, together we will change the face of Edo North and the state in general.
“The aspect that gladdens my heart most is the invitation to Edo North to witness a tsunami of defection that will coast PDP to victory at all levels in 2023,” h
