Chai!!! These BBC guys don't joke around. The show isn't called Hardtalk for nothing. Last month Obasanjo was on the show,president or no president this BBC dude didn't send, and just started interrogating OBJ anyhow.
Former president of Nigeria Olusegun Obasanjo was confronted interviewed about hard pressing issues such as corruption that has been devastating Nigeria and the entire African continent as a whole. Maybe it's just me but if you look in the video up top, like around the 17th minute I think, you can just notice a trickle of sweat running down from the left corner of OBJ's eyebrow.
