I'd put money on him being there - I think he'll feel he owes it to "the country". But I personally wouldn't mind if he wasn't.
At the risk of being called a gloom and doom merchant, it would be unfortunate if he turned up and then didn't win the award. Predictions can be very 'iffy' and a lot will depend on who votes for who on the night - providing that they can actually get through to vote. I tried last year several times during the show but got nowhere, and I seem to recall other MWers having the same problem. That, of course, could have been due to the considerable number of contenders following the Olympics, so maybe it might be easier this time. We should all give it a try anyway!
Thanks for the alert Sparkle.
