Mr Adegbola replaced Mr Moshood Salvador who recently defected to the APC.
Announcing the decision of the National Working Committee (NWC), Eddy Olafeso, the National Vice-Chairman of the party (Southwest), said that Mr Dominic was unanimously chosen by party faithful in the state.
Mr Olafeso urged the leadership of the party in the state to close ranks and forge ahead to ensure victory for the PDP in the forthcoming general elections.
“The declaration today is not to say some people have been defeated or not needed but if we want to allow justice and equity to reign, then it means when we agree on certain principles, the principle must be adhered to the letter.
“The NWC of PDP under the leadership of Prince Uche Secondus, met and deliberated over the circumstances and scenario that we have been dealing with.
“The party so decided, unanimously looked at it, that since we have agreed we are going to start this exco on 35 per cent and 65 per cent (arrangement between the two groups).
“That if there is a vacancy created by one of the two groups, then that vacancy must be filled by those in the percentage where the vacancy is created.
“We took a look at the constitution and what we did is in tandem with the constitution of our party that the vacancy must be filled from the area where it came up.
“In discussing this, we discovered that Dr Adegbola Dominic has been nominated, approved and appointed to oversee the leadership of the party for the role he has played before now and having acted in that capacity for sometime.
“We have written to the Inspector General of Police, Director General of DSS and INEC that from this moment on, the authority and the power of handling PDP in Lagos is given to Dr Dominic,” Mr Olafeso said.
