Swan Lake dancer tripped up

Not starring at the Royal Albert Hall tonight: prima ballerina Polina Semionova . The revered Russian dancer, a graduate of the Bolshoi, had been due to dance as guest lead in 12 performances of Swan Lake (which runs 9-19 June). But she has now been tripped up by the most humdrum of stumbling blocks: problems relating to her visa. English National Ballet are still hoping to whisk her in as a late replacement next week.
