Of course, all our celeb DJs are far too coy about the size of their wads to share the exact figures with us, but it's a sure-fire bet (OK, a Campaign guesstimate) that Mr Tarrant has the biggest wad in the business. Mind you, while Tarrant has reportedly wangled an extra half-hour in bed and lengthy holidays out of Capital, he hasn't added a bean to his salary. However, at £1.3million a year, this was already high enough to put him at the top of our list, and should afford him a comfortable retirement this time next year.
2. NEIL FOX (Capital 95.8 FM)
Foxy's years of loyal service to Capital have seen him rewarded with a package of Garry Lace proportions - around £700,000 a year. Foxy does a lot for his money - he's the voice of the Pepsi Chart, the face of Pizza Hut, the scourge of Simon Cowell and the poor sod who had to front a breakfast show with the disastrous Mel B for two months. Perhaps he deserves more?
3. MIKE OSMAN (Capital Gold)
The comedian and impressionist Mike Osman reportedly earns a whopping £400,000 a year to present Capital Gold's London breakfast show. Unfortunately, we believe he has to pay the wages of his production team out of that - this includes the newsreader Zora Suleman and his brothers, Tony and Harry.
4. TERRY WOGAN (Radio Two)
This time two years ago, Wogan was considering putting an end to his 27-year radio career. Maybe his mind was changed by the enormous popularity Radio Two is currently enjoying. Or maybe he realised he'd miss his £300,000 a year salary just a little too much.
5. JONO COLEMAN (Heart 106.2 FM)
Now that he's shed a few pounds, Jono Coleman really is worth his weight in gold to Heart. Not content with co-hosting London's second biggest breakfast show (for around £250,000 a year, plus all the doughnuts he can eat), Jono decided he would boost his profile with a winning performance in ITV's Celebrity Fit Club. And as if his radio and TV presenting work didn't pay handsomely enough, Jono also writes a column in the Saturday Sport.
6. DARYL DENHAM (Virgin Radio)
The quarter of a million quid Denham reportedly earns each year might seem like a lot to you and me but it represents a saving to Virgin. Chris Evans' breakfast show services were costly (in more ways than one) and his replacement, Steve Penk, didn't come cheap either. Denham joined Virgin as a drive-time host and was dropped into the morning hotseat only 23 days later. While this meant a payrise, Denham is still a steal compared to his predecessors.
7. BAM BAM (Kiss 100 FM)
Congratulations to Bam Bam, who has just received a handsome pay rise. Emap is acutely aware that Bam is one of radio's hottest properties, which is why we think it matched the £250,000 he was offered by a rival station earlier this year.
8. RUSS WILLIAMS (Virgin Radio)
He may not be a household name, but Williams has a CV most DJs would be proud of. He presented Capital's weekend breakfast show for three years and was the voice of the Virgin breakfast for five. He's written two books. He works for the ITV Sport team. And he speaks fluent Finnish and has worked for Helsinki's Radio One. So who are we to begrudge him his money?
9. SARA COX (Radio One)
This year, Cox managed to negotiate a three-year deal with Radio One, which raised her annual salary to £200,000. That's despite losing 700,000 listeners. And getting reprimanded over that Ali G interview. And being rapped for saying on air that the Queen Mother "smelt of wee". Imagine how much she'd earn after a good year.
10. STEVE PENK (Capital 95.8 FM)
OK, so things didn't work out at Virgin. But Penk is still a celebrity who's popping up on TV more and more and is worth a fair bit to Capital. The £150,000 he's reckoned to be on now is a lot less than he earned 12 months ago, but this blow has no doubt been softened by the six figure pay-off we reckon he received from Virgin.
