The BBC "reporting" the news fairly

BBC Radio 4 news at 07:30 leads with the latest Daily Telegraph expenses claims. Four MPs are mentioned: Conservatives Bill Wiggin and Sir Peter Viggers have their claims dealt with in detail whilst the claims of James Purnell and Geoff Hoon are mentioned purely by the statement that they have both disputed the accusations. The BBC might claim that the two Labour Ministers' claims are old news and so the denials are the news element, whereas the claims about the two Conservatives are new news. If we accept that then why was there no mention of the claims surrounding Ruth Kelly?
