The following is a statement issued by the BBC

The BBC has launched an independent review, led by former Head of Sky News Nick Pollard, to determine whether there were any failings in the BBC's management of the Newsnight investigation into allegations of sexual abuse of children by Jimmy Savile.

However, on the basis of material available now, it is apparent from information supplied by the Newsnight editor and programme team - that the explanation in a blog by the editor of his decision to drop the programme's investigation is inaccurate or incomplete in some respects.

By way of correction and clarification:

1.The blog says that Newsnight had no evidence that anyone from the Duncroft home could or should have known about the allegations. In fact some allegations were made (mostly in general terms) that some of the Duncroft staff knew or may have known about the abuse.

2. The blog says that Newsnight had no evidence against the BBC. No allegation was made to the programme that BBC staff were aware of Mr Savile's alleged activities, but there were some allegations of abusive conduct on BBC premises.

3. The blog says that all the women spoken to by the programme had contacted the police independently already and that Newsnight had no new evidence against any other person that would have helped the police. It appears that in some cases women had not spoken to the police and that the police were not aware of all the allegations.

The BBC regrets these errors and will work with the Pollard review to assemble all relevant evidence to enable the review to determine the full facts.

Update 23 October 2012: The BBC has published an additional statement which it issued to Panorama on 22 October 2012. You can read it here.

Back in July we announced that we'd be working with the Knight-Mozilla fellowship for a second year and invited applications from people passionate about working with technology and journalism, and keen to have an impact in this area at the BBC.

My colleague, senior product manager Andrew Leimdorfer, has this update:

We are pleased to announce that we have decided on our new Knight-Mozilla fellow, Noah Veltman, who will be starting with us in January 2013.

Noah is one of eight 2013 fellows who will all be announced at this weekend's sold-out Mozilla Festival in London who will be based in news organisations around the world, including the Guardian and the New York Times.

There are so many ways that technology is changing journalism that our first challenge is going to be to make a choice about which of these areas Noah will be helping us with next year. Working on new data visualisations and developing innovative content for mobile web will be high on the list.

We welcome Noah to the team and wish all the Knight-Mozilla fellows all the best in 2013.

Moving BBC World News, the BBC's largest television channel, from west London to New Broadcasting House in the centre of the city is a huge project that has taken years of planning.

Relaunching and rebranding every hour of its 24 hours of output to give audiences around the world a new exciting polished HD product has made that huge project even more challenging.

Hopefully on Monday at 1200 GMT, the hard work of our 100 dedicated staff will give our audiences a bolder, brighter, more engaging look for the channel they trust to give them independent, objective news and analysis from more correspondents, in more locations, than any other international broadcaster.

Meticulous planning began about three years ago - everything from the new look of our studios to bicycle parking. We tested our studio systems - literally to breaking point - then fixed them and began the dual-running piloting that has split our newsroom teams between those keeping us on air back at Television Centre and those training and developing our programmes in our new home.

We're calling our new location The World's Newsroom because it truly reflects the world we report. We now work with colleagues from 27 language services who report for us from far flung bureaus and in London, allowing us to celebrate their unique expertise - something no other broadcaster can offer.

Audiences have also told us they want to engage more with the stories we tell - to feel closer to the issues we report. We're going to help you "live the story" with us. It's our new channel ethos.

Our correspondents - expert, brave, tough, determined - live and work where they report, and we want audiences to understand their passion for the stories they cover. So expect a new style of reporting from the field. And we'll be everywhere for our relaunch with live and exclusive reports planned from Syria, China, the US and Burma to name just a few.

In the studio, trusted and familiar presenters will be sharing the day's top stories - with a sprinkling of new faces on air. We'll have a more dynamic look, with robot cameras whizzing around our studios, improved graphics and high definition screens to enhance our ability to explain and analyse. We even have some virtual reality surprises planned.

We're also developing new long-form programmes, so expect to see new hard-hitting and timely documentary series. There'll be fresh new editions of favourites such as HARDTalk with Stephen Sackur (our interrogator-in-chief), Click for the latest on tech and Health Check for medical breakthroughs.

BBC World News has come a long way since it launched as a shoestring commercial operation in a backroom at Television Centre more than 20 years ago. Our audiences have grown massively. We're required viewing from the President's White House in Washington to the President's Blue House in Seoul. And in an era when bad mortgages in the US can trigger a global economic meltdown, we know there is a huge appetite for world news delivered fast, accurately and objectively.

We hope you'll enjoy our new look. And we hope you'll join us in the world's newsroom.
