Facebook’s spokesperson, Nick Clegg, says he has found no evidence of a significant attempt by “outside forces” to sway the Brexit referendum. The former party leader of the Liberal Democrats also argued that Cambridge Analytica had little to do with the EU referendum result.

 “We have found no evidence of a significant attempt by outside forces” to sway the vote, Clegg said.

Clegg, who served as deputy prime minister during the first David Cameron cabinet, and an ardent anti-Brexit campaigner, said Facebook ran two studies using data it had in the run-up to the EU referendum using the same methodology to identify Russia’s involvement in the 2016 US presidential elections.

“I’m afraid the roots to British Euroscepticism go very, very deep, and candidly, over the last 40 years, have been much more influenced by traditional media than by new media,” Clegg said.
