More than 400 fake Twitter accounts believed to be run from Russia have reportedly published posts about Brexit.
Researchers at the University of Edinburgh examined 2,752 accounts suspended by Twitter in the US.
They identified 419 accounts operating from the Russian Internet Research Agency (IRA) and attempting to influence UK politics,
The Guardian reported.
Professor Laura Cram, director of neuropolitics research at the University of Edinburgh, told the newspaper that at least 419 of those accounts tweeted about Brexit a total of 3,468 times - mostly after the referendum had taken place.
Commenting on the Brexit tweets, she told the newspaper the content overall was “quite chaotic and it seems to be aimed at wider disruption. There’s not an absolutely clear thrust. We pick up a lot on refugees and immigration”.
