The 33-year-old Sicilian has strongly denied any wrongdoing.In a further storm for the broadcaster at the end of last month, disgraced Huw Edwards pleaded guilty earlier this week to receiving 41 indecent images of children, which included two sexual videos of a boy under nine.The BBC admitted it knew the anchorman – who presented the Queen’s funeral – had been arrested on ‘suspicion of serious offences’ last November, but kept paying his £479,000-a-year salary until he resigned in April.  Tim Davie’s letter in full  Dear all, Firstly I wanted to take this opportunity to say thank you to you all for the tireless work in delivering an excellent summer of BBC content. Across the UK and globally we have produced landmark work. I could list numerous examples but the way in which our journalists in Local, Nations and Network newsrooms reported on the UK riots across TV, radio and online was exemplary, in the face of enormous pressures. The Proms, which end in mid-September, continues to be a spectacular and unique festival that only the BBC can deliver. Also, I want to pay a special tribute to everyone who worked on our extraordinary coverage of the Olympics. We have had a wonderful response and it has brought enormous joy to millions. Overall, audience numbers remain strong including a record number of online accounts being used. Aside from the challenges of delivering such brilliant output, I want to acknowledge that this has been a demanding period for the BBC and everyone who works within it. The shocking news about Huw Edwards and other stories, concerning some of our high profile shows, have put the BBC in the spotlight. It can be challenging for us all when the BBC becomes the headline. We work for this wonderful organisation because we care about what it stands for and the role it plays in society. I know we have all felt let down and worried about the impact on the BBC. However, we hold ourselves to the highest standards and we know there will be lessons we can learn to ensure we have the strongest possible workplace culture. I very much welcome the proposed actions that the Chair outlined in his recent email, and I want to thank everyone for their calm support as we have navigated a tough situation. Our aim should be to act fairly, in line with our Values, and work to build trust. Personally, on my watch, building a positive culture and making the BBC a great place to work is a critical priority. I know that many people are proud of their teams and feel they are working in a supportive and positive environment. We must make that universal. Finally, I hope that many of you have taken a chance to get a well-deserved break in recent weeks. It’s going to be a busy autumn as we deliver a strong programme of content while continuing with our plans to transform the organisation and grow it for the future. I look forward to getting out to see many of you in the next few months across the UK and beyond. Best wishes, Tim   This is a breaking story, more to follow.
