Adediran polled 79 votes while Sanwo-Olu secured 66 votes. Rhodes-Vivour, however, got just one vote.
In the House of Assembly election, PDP polled 81 votes against 76 polled by the APC, as the Labour Party scored a single vote.
While addressing journalists after casting his vote, Adediran expressed optimism in securing victory at the polls.
He said, “I feel there is a need for us in the state of Lagos to stand up and see how we can put an end to a dynasty that hold us in the jugular for over two decades and since we have started this project, to the glory of God, we have done everything as a human being.
“We have been consistent and we have been so focused over the years and we have been able to make that huge statement by making sure we are on the ballot. Since October last year, we have not stopped campaigning, so we are very optimistic. We know we will win this election.”
Asked what he would do if he loses the election, he said, “This election is a process, if we win we will go to the next process. If we win again, we will go to the next process.”
Earlier, a former deputy governor of Lagos State, Sarah Sosan, declined to speak on the chances of APC candidates after casting her ballot at the polling unit.
When asked if she would deliver her polling unit for APC, Sosan, an APC chieftain who shares the same polling unit with Adediran, said, “I am not commenting on that.”
