David Cameron said on the BBC’s Andrew Marr show that search engines such as Google need to do more to block results for ‘depraved and disgusting’ searches for child abuse.
Cameron said: "I think it's wrong that they should get results and we need to have very, very strong conversations with those companies about saying 'No, you shouldn't provide results for some terms that are so depraved and disgusting'.
"I think there's going to be a big argument there, and if we don't get what we need we'll have to look at legislation."
The discussion today comes ahead of a speech the Prime Minister is expected to make tomorrow, which will put forward a plan by the government, including having a ‘blacklist’ of words provided to search engines by the Child Exploitation and Online Protection Centre.
Anyone searching for terms on this list will be made to view a webpage warning them of the consequences of their actions, which could include losing their job and access to their children, according to a snippet of the speech seen by the BBC.
Google says that when child abuse images are found, it acts to remove them.
