I have been out all day, so I am late coming to this. To be frank, I haven't the time to read every reply, but I am not in the least bit surprised that he will not be involved in Top Gear any more.
If he and his million fans thought that it was OK to assault a work colleague, and get away with it, then they are sadly mistaken. The issue of his fame and whether the program will survive without him is neither here nor there. The BBC have done what any other employer would have done and should have done.
We will soon find that Clarkson isn't unique or irreplaceable. There are plenty of others that can do the job.
But this isn't about Top Gear....its about dealing with an assault in the workplace, and this incident should be treated just the same as any other of the same kind.
