Simone Clarke, the principal dancer of the English National Ballet, has provoked renewed outrage after taking an executive role with Solidarity, a union that critics link to the extreme-right British National Party (BNP).

Clarke was exposed by the Guardian newspaper earlier this year for having a membership in the BNP, which has been deemed anti-immigration and racist by critics.

The 37-year-old dancer was blasted by critics, who called for her removal from the English National Ballet. Anti-racism protesters picketed her outside the theatre where she was performing in the national ballet's production of Giselle.

The English National Ballet released a statement during the controversy, saying "any personal view expressed by one of our employees should not be considered as endorsed by the company."

While the uproar seemed to pass as the year went along, Clarke has taken yet another contentious step.

She has been elected to the executive board of Solidarity, a trade union that aims to protect the rights of British workers. 

Some artists' unions have expressed their disappointment with Clarke over her election to the board.

Clarke posted a statement on Solidarity's website.

"Last year a newspaper 'exposed' my BNP membership. Some politically motivated malcontents tried to have me sacked, hence my interest in a British workers' union."

Solidarity's general secretary is Pat Harrington, a well-known far-right activist and former National Front organizer. Critics say the organization is a front for the BNP, but Solidarity officials say they are an independent trade union.

Clarke, whose partner is a Cuban of Chinese extraction, has said the BNP was the only party that took a stand against mass immigration.

"Some of the things [the BNP] mentioned were the things I think about all the time, mainly mass immigration, crime and increased taxes," she confirmed in a weekend interview with the Mail on Sunday newspaper.

"I've never been clearer in my head that I'm moving in the right direction and at the right time."
