For me, he's the worst part of the show.
Hats off to Tess for doing a sterling job.
This isn't an ageist thing, it's about an individual's ability to do a job, and in my opinion, Bruce hasn't been up to the job for the last three series.
I'm sure there's a programme somewhere that would benefit from Bruce's special brand of presenting (fumble, repeat, humiliate guest, refer to his age etc) but live, primetime Saturday night really isn't the place.
