There seems to be some confusion in your statement. As of my last knowledge update in September 2021, Bola Tinubu is a Nigerian politician and former Governor of Lagos State. However, there is no information available regarding him participating in the G-20 summit or holding the position of President.
Please note that political situations and positions can change, and my information might be outdated. I recommend verifying the latest news from reliable sources for accurate and up-to-date information on Bola Tinubu’s political activities and roles.
