The Guardian’s Julia Day on a rival tabloid’s successful effort at uncovering just what the public license payers are getting for their money.

BBC sources fear that revelations in the Sun about the Radio 1 breakfast DJ Chris Moyles’ (above) £630,000 annual salary and soap actor Ross Kemp’s £380,000 pay packet could be the tip of the iceberg and more of the corporation’s stars will have their wages laid bare.

The corporation believes a BBC insider may have accessed a computer database containing extensive staff salary details and is investigating where the security lapse could have occurred.

The salary details of eight of Radio 1’s highest-profile DJs were published today in the Sun, putting Moyles as the top earner, while dance DJ Pete Tong gets £70,000.

Mid-morning host Jo Whiley is cited as earning £250,000, compared with Sara Cox’s £200,000 for two weekend shows a week, while double-act Edith Bowman and Colin Murray are said to earn £175,00 and £170,000 respectively. Scott Mills and Zane Lowe earn £130,000 apiece, according to the Sun’s report.

Last month the same Sun reporter, Julie Moult, revealed the salaries of a host of EastEnders’ stars, including Barbara Windsor’s and Steve McFadden’s £360,000 pay packets, and Dot Cotton actor June Brown’s £370,000 salary.

The only silver lining to this story is that Moyles might have replaced Carlos Boozer as the most overpaid man on the planet.
