Three people have been charged with racially aggravated public order offences after a group heading to a far-right British National Party camp on Saturday taunted anti-racism protesters, police said.
Derbyshire police arrested 19 people during the mainly peaceful anti-BNP rally near a farm outside the village of Codnor where the BNP's Red, White and Blue festival was held over the weekend.
The three were among a group who crossed fields to get to the camp on foot under police escort as hundreds of demonstrators waving placards saying "the BNP is a Nazi party" blocked road access to the site.
The BNP, which campaigns to halt immigration and repatriate immigrants voluntarily, won its first two seats in the European Parliament in June.
Although it has no representatives in the British parliament, the party has won support from white voters angry about unemployment and access to public housing and other services during the worst recession in generations.
