Coldplay lead singer Chris Martin today launched an attack on his record label EMI and the company's shareholders.

It came after EMI, the world's third-largest music company, warned that profits would be lower because the band took longer than expected to finish their first studio album in three years.

But as Coldplay prepared for a concert in New York to promote their new album, called X&Y, Martin said: "I don't really care about EMI. I'm not really concerned about that.

"I think shareholders are the great evil of this modern world."

He criticised what he called "the slavery that we are all under to shareholders".
