What does the government mean by 'far right'?

Today, the government labels all those who are taking part in the riots as ‘far right’. Some of them I guess, most of them are actually ‘far right’, although I think some of them actually haven’t even really thought out any ideologies. They’re doing it because that’s what they feel like. But there’s a growing number of people who don’t take part in riots yet are also saying “enough is enough” when it comes to mass migration and multiculturalism.
