Businesses have been urged to boycott social media firms until they crack down on terror, a report into the 2017 terror attacks says.
The Intelligence and Security Committee of Parliament (ISC) - chaired by Dominic Grieve MP - published two reports on Thursday, analysing the Westminster, Manchester Arena, London Bridge, Finsbury Park, and Parsons Green terror incidents.
Thirty-six lives were lost and many more were injured during the attacks last year, and the report considers whether mistakes were made, and seeks to ensure that all changes and improvements required have been identified.
In it, MPs said: "The system for regulating and reporting purchases of the ingredients used to make explosives was hopelessly out of date. This facilitated the perpetrators in acquiring the materials they required."
