Twitter accounts linked to Russian 'troll factory' active in Brexit referendum

Twitter has found 49 accounts linked to a notorious Russian "troll factory" which were sending out messages about the EU referendum during the 2016 campaign.

The company's UK head of public policy Nick Pickles told a House of Commons committee that the accounts linked to the St Petersburg-based Internet Research Agency amounted to less than 0.005% of those tweeting about the referendum, and received "very low levels of engagement" from other users.
