From Nigel Farage
Q. An American friend of mine has just landed a top job. I am really pleased for him but no one else seems to think that it is a good idea. How do I persuade the doubters that he is a good guy really?
A. Why not suggest to your friend that he starts tweeting? Obviously, as he is a good guy, his natural amiability will shine through and the doubters will soon be singing his praises.
