When German politician, Wolfgang Bosbach, found out he was going to be on the celebrity version of 'Who Wants to Be a Millionaire?', he probably thought he could do a lot worse than having the German Chancellor as his 'phone a friend'.
After all, Chancellor Angela Merkel is an intelligent lady who probably stays calm under pressure.
