 The head of Russia's Bolshoi Theatre has been removed from his post, following a series of scandals including an acid attack on the ballet company's artistic director. 
  
 Anatoly Iksanov is to be replaced by Vladimir Urin, the Russian culture ministry announced. 
  
 The acid attack on Sergei Filin exposed vicious internal rivalries at one of the world's top ballet companies. 
  
 Culture Minister Vladimir Medinsky said the Bolshoi needed "renewal". 
  
 "A difficult situation had developed around the theatre and the troupe - everything pointed to the need for renewal," he said. 
  
 Mr Iksanov had been accused of mismanaging the Bolshoi's $1bn (£860m) renovation - which ran years over schedule and over budget. 
  
 He had also become embroiled in a war of words with dancer Nikolai Tsiskaridze. 
  
 Mr Tsiskaridze, a principal dancer and teacher at the Bolshoi, complained of corruption and called for the theatre's entire management to be sacked and for himself to be put in charge. 
  
 Nikolai Tsiskaridze demanded he be put in charge of the Bolshoi 
  
 Mr Iksanov hit back, suggesting Mr Tsiskaridze might have played a role in inciting the attack on Mr Filin, which left him with severe burns to his face and almost completely blinded. 
  
 Mr Tsiskaridze has denied having anything to do with the attack, for which three other people are awaiting trial. 
  
 But he has been told his contract at the theatre will not be renewed. 
  
 Mr Iksanov had been the head of the Bolshoi Theatre for the last 13 years, and had more than a year of his contract to run. 
  
 Culture Minister Mr Medinsky said he would still have a role advising his successor, Mr Urin, who has been general director of the Stanislavsky Musical Theatre. 
  
 Mr Urin "will be able to unite the troupe and continue the development of the best theatre in the country and one of the best in the world," Mr Medinsky said. 
  
 Commenting on his appointment, Mr Urin said "I don't plan any revolutions and understand perfectly that in this theatre, as in any other, one person alone cannot do anything. 
  
 "I very much hope that the majority of people working in this theatre - talented, remarkable people - will be my allies," he said. ||||| The Russian culture ministry on Tuesday fired the director general of the famed Bolshoi Theater that has been mired in scandal since an acid attack on its artistic director.

 Anatoly Iksanov would be replaced by Vladimir Urin, head of another major ballet and opera troupe, the Stanislavsky and Nemirovich-Danchenko Music Theater, said the culture minister, Vladimir Medinsky. 
  
 He said that a "difficult situation at the theater" was the reason for the dismissal. Iksanov, however, was offered to work as Medinsky's adviser in the ministry. 
  
 The Bolshoi has been shrouded in scandal for years but a fierce conflict erupted in January when an assailant threw acid into the face of Sergei Filin, the artistic director of ballet. 
  
 In March, police arrested Bolshoi soloist Pavel Dmitrichenko over his involvement in the attack. Dmitrichenko admitted that he had agreed to an offer from an acquaintance to rough up Filin, but he insisted that the man had used acid on his own initiative. Despite Dmitrichenko's confession, many in the ballet company have stood by him, saying they do not believe him capable of staging such a crime. About 300 dancers and staff, led by principal dancer and Iksanov's key opponent Nikolai Tsiskaridze, signed an open letter claiming that Dmitrichenko had slandered himself under police pressure. 
  
 The Bolshoi reopened in 2011 after a $1 billion renovation. Despite the lavish sums, some of the work was of poor quality, with cracks appearing in the walls and gold leaf crumbling away. 
  
 Iksanov has been at loggerheads with many of the troupe's famous dancers, including Tsiskaridze who accused him of mismanaging the Bolshoi's reconstruction, ruining its repertoire and abusing dancers' rights. Iksanov and his backers have dismissed the criticism. |||||
Output:
Russia's culture ministry has fired the director general of the scandal-plagued Bolshoi Theater. After a January acid attack on artistic director Sergei Filin and amid claims of pimping at the ballet, the country's culture ministry is replacing director general Anatoly Iksanov, the AP reports. Culture minister Vladimir Medinsky said that "around the theater and the troupe—everything pointed to the need for renewal," he said, per the BBC. But all isn't necessarily lost for Iksanov: The same ministry that's firing him has offered him another job as an assistant to Medinsky. Iksanov had headed the theater for 13 years and had more than a year left in his contract, the BBC notes. Taking over the director general job will be Vladimir Urin, who runs the Stanislavsky and Nemirovich-Danchenko Music Theater, another top ballet and opera company, Medinsky says. In addition to the scandals, Iksanov faced criticism over the Bolshoi's $1 billion renovation, and he was at odds with top dancer Nikolai Tsiskaridze, whose own contract won't be renewed.
