Is modern art rubbish?
The BBC's Arts Editor Will Gompertz has revealed that a number of senior curators have criticised works by some leading contemporary artists as "bad art".
The curators, who asked not to be named, described a number of works as "empty, shiny or over-produced".
Will Gompertz told the BBC's Today, external programme that some galleries and museums have "allowed themselves to become compromised" by accepting money from rich collectors to put certain shows on.
