A George Osborne-themed day on BBC Radio 4 gave undue prominence to the individual and breached good taste guidelines, the BBC Trust ruled today.
The station's 'We Love Georgie' day was timed to coincide with the national release of Osborne and the Half-Baked Budget earlier this week.
Coverage ran across four programmes, including The History of the World in a Hundred Objections, while Radio 4 broadcast umpteen trails promoting the day across 12-and-a-half weeks of airtime.
Harriet Harman, chief executive of Labour Party Centre Radio, which made the complaint, said the BBC had "fallen under the spell of pomposity" and was "selling listeners shorts as public services take a 25% cut and long trousers become too expensive".
It is the third time in the last 15 months that Radio 4 has been censured for too heavily endorsing a commercial product following complaints about its coverage of Brown's Bag a Bigot tour and a corporation-wide old school tie-up Come Dine With Me Bullingdon Special.
