The leaders of a far-right British party, one of whom acquired extensive attention after a message she posted online was retweeted by US President Donald Trump, have actually been discovered guilty of consistently aggravated harassment.

Paul Golding, 36, leader of the anti-immigration Britain First celebration, and his deputy Jayda Fransen, 31, were founded guilty of shooting and bothering people they thought were included in a rape trial involving a variety of Muslim males at a court in Kent.

They published their actions on the Britain First website as well as delivered offensive leaflets to houses in the area where those included in the case lived, district attorneys told Folkestone Magistrates Court.

“The prosecution case showed these offenders were not simply exercising their right to complimentary speech but were instead intending consistently exacerbated abuse at innocent members of the public,” Chief Crown Prosecutor Jaswant Narwal said in a declaration.

Golding was imprisoned for 18 weeks and Fransen 36.

Last November, Mr Trump retweeted anti-Muslim videos published by Fransen, drawing condemnation from across Britain including Prime Minister Theresa May.

Mr Trump at first fired back at Ms May, saying she needs to concentrate on “the destructive Radical Islamic Terrorism that is occurring within the United Kingdom”, but in January he stated he had not planned to cause offense in Britain and his retweet was not a recommendation.

“If you’re telling me they’re awful people, horrible racist people, I would definitely apologise if you would like me to do that,” Mr Trump said in an interview with a British broadcaster.

Fransen, who was convicted last year for abusing a Muslim woman, said at the time she thought Mr Trump had actually been “railroaded” into making an apology.
