How can anyone think the possible end of Sir Patrick's tenure wasn't foreseen by the controllers and other 'powers'? .
.. because we are talking about the BBC.
I think Brian will add to the SaN more than Chris. That is not to say Chris would not make a good presenter, I think he would, but Brian has the x-factor!
,,,,,only joking, I think Brian has qualities that would appeal to more of the audience without dumbing down in the slightest. Of course it comes down to taste, but Brian ticks all the important boxes for me (as long as has presenting skills).
