Watch prof osinbajo 6th presidential quarterly business forum

I'm happy to help! However, I need to clarify that Prof. Yemi Osinbajo is the Vice President of Nigeria, not the President. Therefore, he wouldn't be hosting a Presidential Quarterly Business Forum.

But, if you're interested in watching a video of Prof. Osinbajo speaking at a business forum or event, I can try to help you with that. Could you please provide more context or specify which event you're looking for?
