YouTube has been criticised by MPs, who say it must do more to vet its content.

In a review of net safety, the Culture, Media and Sport select committee said a new industry body should be set up to protect children from harmful content.

It also said it should be "standard practice" for sites hosting user-generated content to review material proactively.

The committee acknowledged that the volume of content on sites such as YouTube - which has 10 hours of videos uploaded every minute - made it unrealistic to watch every video before it went online.

But, it said that the practice of removing clips only after they are flagged up by users was not working either.
