Prime Minister David Cameron has warned internet companies they must act to block access to images of child abuse online or face stricter legal controls.
Speaking to the BBC's Andrew Marr Show, he said firms like Google had to do more to block "depraved and disgusting" search terms.
Google said when it discovers child abuse images it acts to remove them.
