According to the Telegraph:
Almost 400 people said the Corporation had given the events too much airtime and more than 150 claimed the broadcasts had been too favourable towards Benedict XVI. However another 200 viewers believed the coverage on news bulletins and documentaries had been too critical, while more than 100 praised the BBC for its work.The BBC says on its website:
The visit by Pope Benedict XVI was the first ever State visit by a Pontiff and was of huge historic significance to millions of Catholics and other people in the UK. It was entirely appropriate that the BBC, as the nation's broadcaster, would provide coverage of the event.
The Pope's Visit 2010 has to a certain extent divided public opinion and been the subject of much debate. In order to offer both balance and perspective to this historic occasion, the BBC marked the visit with coverage of the five major ceremonies across BBC television, radio and online, as well as using documentaries and other output to look at different aspects of the Catholic Church's affairs. As is absolutely right for an independent news organisation, this included transmitting some programmes which investigated issues that have negatively affected the Catholic Church, such as the recent child abuse scandals.
In its News and Current Affairs coverage of any subject the BBC is always committed to impartiality and accuracy, seeking also to reflect the different sides of any debate. The coverage of the current Papal visit was no different, and careful planning went into making sure that we provided the most comprehensive and authoritative coverage for our audiences.
