This thread is beneath contempt. You can't even be bothered to spell your thread title correctly.
Who is the worst number one is a question of absolutely no importance. If it is of interest to you, you can look up who was ranked number one while holding the fewest ICC rankings points (which you haven't even bothered to do!). There can be no debate on the matter, and so there is no point having this thread.
I would also make the point that the worst number one - whoever it was - was still the best team in the world. In other words, to paraphrase Churchill, they were the worst team - apart from all the others.
