I agree entirely about the power that digital television brings. Last year, we changed the core receiver requirements under the digital switchover help scheme to give single-button access to audio description services, and we are looking at this all the time to see how we can go further. My hon. Friend and I attended a reception in the House with the Royal National Institute of Blind People, which is campaigning to go further on audio description targets. As I said, Ofcom is looking at the issue, so I will have to wait for its review, but he may know that Sky announced last week that, from the beginning of this month, it will voluntarily double its target to 20 per cent. I should like other broadcasters to follow that lead and voluntarily and independently increase the amount of audio description, but we will follow through with Ofcom and come back to the issue later in the year.
