Tech firms have been urged to show that they are removing extremist content more rapidly or face legislation forcing them to do so, new EU guidelines reveal.

The EU has unveiled a recommendation that sets out measures to ensure faster detection and removal of illegal content online. They include:
Clearer 'notice and action' procedures: Companies should set out easy and transparent rules for notifying illegal content, including fast-track procedures for 'trusted flaggers'.
