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.

This week viewers to BBC World News have been watching a series of reports focusing on the Arab uprisings, two years after they first began. Correspondents have been in Damascus, Tunis, Cairo, the Syria-Lebanon border and elsewhere. Their eyewitness TV reporting is accompanied by further explanation and analysis on our website, bbc.com/news. These are expert journalists, with years of experience and knowledge, living the story on behalf of the audience. They demonstrate our commitment to reporting the world, and bringing clarity to complex events.

Until now, however, viewers in the world's biggest TV market, the US, have found it hard to access BBC reporting of this kind. The market is saturated with TV channels, but for the past couple of years we've been very focused on securing widespread carriage on the distribution systems which bring TV into most homes.

So today the BBC is delighted to announce we have agreed to a partnership with the US cable giant - Time Warner Cable - and through this and other deals, a further 10 million homes in the US will have access to BBC World News 24 hours a day, seven days a week.

This means by the end of this year we will be available in 25 million homes, including those in most of the major markets - New York, Washington DC, Los Angeles, Chicago, Boston. There is still some way to go before we can say we have reached everyone - but 2012 has been a year of significant breakthroughs for us in the US.

The BBC is already well-known in America through its partnerships with public radio, through the success of our website BBC.com/news, and because of our nightly broadcast on public television fronted by Katty Kay. We believe our brand of high-quality, intelligent and non-partisan journalism has something to offer US audiences, and we're determined to make access to our services as simple as possible.

The timing could not be better. We're just a few weeks away from the first broadcasts of BBC World News from our brand new headquarters in central London. Three new studios, a big investment in production and journalism, and working more closely with BBC journalists working in English and 27 other languages - it's more than just a new home, it's a new start. We're delighted to share that even more widely.

It is no secret that recent Arab uprisings have placed enormous burdens on the shoulders of BBC Arabic journalists responsible for reporting news from the region.

Covering the Arab world is not always an easy task - we need to mix sensible caution with a dose of courage in covering political issues that attract so many disputed views among Arabic-speaking audiences.

Our guiding principles are the BBC's values, its editorial guidelines, its ethical code, which are our reference points to maintain impartial, balanced and accurate reporting.

Across the Arab world - whether it's Tunisia, Yemen, Egypt or Libya, Bahrain, Syria and Iraq or the many other countries in the region - we know that audiences want access to objective and independent news, far removed from an agenda that favours one party, religion or sect against another. That is why audiences are turning to BBC Arabic.

Last year, our latest figures show that overall audiences to BBC Arabic have risen by more than 17% to a record high of 25.3 million adults weekly. That includes a big surge of 2.9 million in Saudi Arabia and 2.7 million in Egypt, where TV viewers in particular turned to the BBC to better understand the events happening in their own country. Our radio audiences are also holding up despite the reductions in transmission. Online is proving to be more of a challenge, but we are working hard to understand the needs of digital audiences and those for whom social media plays an increasingly important part in their lives.

In 2011, following the fall of the Mubarak leadership, we watched as ordinary Egyptians carried banners saying "Thank you, BBC!" But meeting the high expectation of audiences has a price and sometimes it's been a heavy one.

March 2011 brought a strong reminder of the risks that our staff face in covering the news - one of our reporters was arrested and tortured by Muammar Gaddafi's forces during the Libya uprising. In early 2012, our reporter in Yemen was beaten and received death threats from supporters of the outgoing president.

We are also challenged by those who disagree with our coverage. In countries such as Syria and Bahrain, BBC Arabic has been accused of bias.

The criticism comes from opposition and government alike. It may be a valid argument to say that getting criticism from both sides, in the case of Arab world certainly, is an indication of balanced coverage.

On Syria, for example, we had a series of documentaries looking at the civil war from a number of perspectives.

The first one, exploring what it's like to work for a Syrian television channel that's the mouthpiece of the government, was the butt of criticism and threats from Syrian opposition quarters. We followed it up with a programme charting a day in the lives of six Syrian women, five of whom were anti-government activists.

In our day-to-day news coverage, presenting a variety of voices from Syria is essential to us. And that is what distinguishes BBC Arabic from many media outlets in the Arab world which promote political views and agendas, and that is what we are determined to keep.

BBC Arabic marked its 75th anniversary in January. Arab politicians and ordinary people have expressed their appreciation of our track record of impartiality and trusted news. I am confident that the coming years will see further achievement on all our platforms - TV, radio and online.

We are busy doing some research and thinking at the moment about what people are looking for in our News apps in the longer term, but we thought that in the meantime, it was important to fix one or two bugs affecting some users of the existing app and to make it a better, slicker experience overall.

We want to make sure the current app remains a great way to get a quick overview of the top stories across a wide range of subjects, easy-to-scan on a mobile and, once the stories have loaded, handy to read offline too.

So, it will now be quicker to start up the app and to update it, and it should feel smoother and faster as you scroll and swipe through the screens and stories.

The larger homescreen images we've introduced serve two purposes:

• first, you can see what's in them more clearly and there's more room for the headline
• second, their positioning makes it clearer that you can scroll horizontally in each news category to reveal more stories (we noticed that in user testing some people assumed there were only three stories a section).

There is a new layout on iPad when you view the home screen in portrait mode - designed to show more headlines and make it easier to find the stories you're interested in.

Among the bugs that we've fixed is an issue that sometimes caused the app to get stuck when updating, and another where you sometimes saw duplicate stories within a single news category.

For our product team, these improvements required a fairly major reworking of the app's code. The good news is that they are now working from a more stable base which can be built on with new features and functionality. This revising of our code is something we've already done with our Android app, so we'll now be able to release upgrades simultaneously on both iOS and Android, which are by far the largest mobile platforms for us in terms of users. This latest update is already available internationally.

If you're a user of the app, or decide to try it out, we hope you'll like the improvements we've made. And as we think about our apps generally and plan our next steps, we'd like to hear about what you'd most like to see in future.
