(MENAFN- Arab News) WELLINGTON: New Zealand's ruling National Party is being sued for alleged unauthorized use of rapper Eminem's song 'Lose Yourself' in campaign ads ahead of next Saturday's general election.

Detroit-based Eminem Publishers said in a statement Tuesday it had started court proceedings in New Zealand.

'The proceedings stem from allegations that unauthorized use has been made of Eminem's Grammy and Academy Award winning song 'Lose Yourself' in election campaign advertising run by the National Party' the statement said.

Lawyer Garry Williams told Fairfax Media it was the owners of the song not Eminem taking the action.

The National Party said in a statement it rejected the allegation saying it purchased the music from a recognized production music supplier and was assured it did not infringe any copyright and was an original work.
