Prince Harry's legal battle against British tabloids has entered its final round. His lawyer on Monday alleged that the Daily Mail engaged in unlawful information gathering for two decades. Harry claims this left him distressed and paranoid. The case also involves celebrities Elton John and Elizabeth Hurley. The trial in London’s High Court is expected to last nine weeks. Associated Newspapers denies the allegations, arguing that the claims are based on weak inferences. The defense also suggests that articles relied on “leaky” friends as sources. The privacy invasion case is the third lawsuit Harry has brought against the press.
