The hon. Gentleman mentioned YouTube, and I think—if I remember the number correctly—that it has removed something like 300,000 pieces of terrorist material. There is, however, a lot more that needs to be done not just by YouTube, but by many other internet companies. There is already an ability for the Government or, more likely, the police and other trusted organisations to flag up certain content on the internet, whether videos, stills or other types of content. So far this year, we are seeing a marked improvement in the speed with which that content is being taken down. In many cases, it is being taken down within the hour.
The hon. Gentleman may be interested to know that what has also grown considerably in relation to taking down content is the use of machine learning—trying to have the right algorithms to take down content much more quickly. For example, Facebook removed some 1.9 million pieces of content in the first quarter of this year, which is up some 70% on the same quarter of last year. In many cases, the content is being removed within minutes, and in some cases it can be stopped even before it is uploaded.
