Emmanuel Ada Ogejuma is a pharmacist and award-winning sales manager.

My weakness is my insatiable drive for success.

Emmanuel Ada Ogejuma, regional manager GlaxoSmithKline

He is responsible for the sales of HIV drugs and vaccines in Nigeria for pharmaceutical giant GlaxoSmithKline (GSK) - a key corporate sponsor of the leadership project.

But Emmanuel is not just well-known at GSK for his own success; he is also seen to help team members develop in their careers.

His smooth talking and laid back personality will be tested, so can he keep a cool head and bring his skills to bear on this leadership mission?
