The world's great sopranos are not the only prima donnas at La Scala. In the latest fit of pique among its performers, ballerinas in the celebrated opera house's latest production of Roméo et Juliette have gone on strike after management refused to pay them more for dancing on a sloping floor.
They've been joined by the choir after singers complained the plans for them to perform simple movements to coincide with Sasha Walz's choreography was a step too far; or at least one that merited a Christmas bonus.
As a result of the row, today's opening performance of the production has been cancelled.
"For its part, the dance corps believes that the difficulty of dancing on a sloping platform should be compensated with a concrete bonus," said a statement for the ballerinas

Mauro Peconi, spokesman for the choir, said: "It's a special situation. This has to recognised."
But La Scala management said the artists were "not being asked to do anything different to what would normally be required in a seasonal show.
