My comparing the choice between having a pint with Clarkson or Portillo was by no means suggesting either would be desirable, but if a choice needed to be made...
He is an obnoxious twat.
Portillo on the other hand doesn’t try to be a comedian, or on the edge of opinion, he’s just a bloke presenting a programme for something he’s passionate about. He’d probably be a far easier person to share a pint with than Clarkson.
