OK, nothing really new, but the majority of the time it was just a suspicion without any real proof.
Just a few minutes before 8am when there was a discussion about the intention by the BBC Trust to get the BBC management to release figures for all highly paid staff, and some disclosure over what the 'talent' earns, too, one of the interviewees (journalist who wanted to see Jonathan Ross) commented on the highest and the lowest paid (and then about how he was getting paid 50 pounds for being on the radio).
Yes, I know he may well have needed to be waiting on the line for 10 minutes, and ready to be called another 10 minutes before that, so the 50 quid isn't for just the 2-4 minutes he was on air, but it seems likely that Today spends a couple of hundred pounds a day - may be as much as 60K per year, for speaking to 4 people each day they broadcast. I assume Thought for the Day speakers get a similar fee, and someone on BBC Radio 2 (around 03:30 and 04:30 from memory - I use the time to make a cuppa or go to the loo,) too.
Then you have to wonder how much someone on a TV news show (or current affairs) earns for a few minutes on TV...
