London, Jul 3 : Italian born actress Greta Scacchi, who posed naked with a cod as part of a campaign to save the world's fish stocks, has said that it takes a celebrity to get the Government to take notice of a cause.

Scacchi, 49, was left bemused to have been invited to talks at the Department for Food, Environment and Rural Affairs with Huw Irranca-Davies, the Environment Minister, as the Marine Bill makes its way through Parliament.
