Robbie Williams may be able to rely on an insurance policy to cover the damages he will have to pay a US song publishing company after the High Court found that he had copied a "substantial" amount of another song.

An account handler at a Lloyd's insurer said that Williams's liability could be covered by an "errors and omissions" policy.

But this kind of policy would usually only cover damages and not any legal costs.

"It is quite common, or should be, for established stars to take out this kind of insurance," the account handler said.

The court decided that Williams's song "Jesus in a Camper Van", was a breach of copyright of the song "I am the Way" by the late US folk singer Woody Guthrie.

Williams and his record and publishing companies now face a trial to establish the amount of damages.
