The National leader of APC and Former Governor of Lagos Bola Tinubu as issued a rare statement endorsing Mr Sanwo-Olu ahead of the gubernatorial primary elections.
In a statement obtained by TVCreed Asiwaju Bola Tinubu listed some areas he considered critical to the advancement of Lagos but which Gov Ambode strayed in his over three years in office.
He said the governor abandoned a Lagos developmental blueprint he initiated while in office between 1999 and 2007, as well as claims that the governor did not consult broadly before taking key steps in his administration.
Tinubu had largely avoided openly abandoning Gov Ambode, even though speculation had been rife about his preference for Mr Sanwo-Olu for several weeks.
Gov Ambode has not replied Tinubu, but the governor has insisted that he would not back down to a growing chorus for him to step down to avoid being humiliated at the primaries.
The APC national executive had postponed the primaries for Lagos twice within the last week, amidst concerted moves to strike a truce between Messrs Sanwo-Olu and Ambode.
