Dino Melaye, a senator from Kogi west, says he will not apologise to Oluremi Tinubu, his colleague from Lagos central and wife of Bola Tinubu, the national leader of the All Progressives Congress (APC).
Melaye said this at the executive session of the senate on Tuesday.
In a closed-door session of the senate last Tuesday, Melaye and Tinubu had engaged in a brawl over an issue regarding the trial of the presiding officers of the upper legislative chamber for alleged forgery of the senate rule book, 2015 at an Abuja high court.
