Let it die, it had passed it's sell by date anyway. Clarkson is what sold it to the rest of the world. No doubt the BBC will try and recoup the hundreds of millions they will lose by producing some edgy watered down trendy version though.
Will be interesting to see if Clarkson wants to continue with someone like Sky and compete with the BBCs new version.
Is it? I have no idea which countries produce their own editions and which ones take the UK edition but I can't image that many being that bothered about Clarkson, May and the little tit Hammond.
I think it will do fine without him or the three of them, I haven't watched it for years as it got boring and predictable. Perhaps with a new presenter or group of presenters it will do ok.
There will obviously be a large number of people out there who want it to fail, either BBC bashers or Clarkson apologists, who will be saying how s'hite it is whatever happens.
