Yulia Navalnaya, who heads the US-based Human Rights Foundation (HRF), urged people not to underestimate the threat that "very dangerous" dictators and their networks pose, arguing they can "only be defeated if those who fight for freedom cooperate too".

"They learn from one another, they work together," she told journalists in London at the launch of the new report, which finds European far-right parties are increasingly coordinating with authoritarian regimes beyond the continent.
