Why does BBC Trust support Radio I’s decision to cut down the song Ding Dong?

The BBC Trust has rejected a complaint about Radio I’s decision to cut down Ding Dong! The 74-year-old song, which first appeared in the soundtrack for the Wizard of Oz film, made a surprise chart entry in April as a form of protest by critics of the late Conservative prime minister. It’s described as an inappropriate "celebration of death". The BBC Trust’s editorial standards committee rejected the complaint, saying that the song did have the " capacity to cause offence" because it had been widely publicised as a way of giving voice to"anti-Thatcher feelings".
