A dossier of evidence obtained by BBC Newsnight from an ex-policeman hired by the News of The World (NoW) shows the newspaper was engaged in covert surveillance on a huge scale.

Over eight years Derek Webb was paid to follow more than 100 targets. They included Prince William, Prince Harry's ex-girlfriend Chelsy Davy, former attorney general Lord Goldsmith and football manager Jose Mourinho.

The paper's owner News International said it was not able to comment.
