May issues fresh warning to social media firms about terror content

Theresa May is calling on investors to put pressure on tech giants to deal with illegal content on social networks.

She is asking investors to consider the social impact of the firms they support, and to pull support if firms refuse to remove extremist and criminal content from their networks.

The prime minister is also keen to see more UK firms focusing on artificial intelligence, since Britain already has a "cutting edge" when it comes to AI innovations.
