Prince Harry has escalated his privacy lawsuit against the Daily Mail’s publisher by alleging unlawful “blagging” targeted his brother Prince William and Kate Middleton.

In Thursday’s High Court hearing, Harry’s lawyers claimed Associated Newspapers used deceptive tactics to snoop on William’s 21st birthday party and other private matters, joining claims from co-claimants like Elton John.

The publisher dismissed the accusations as “preposterous,” pushing to strike out parts of the case as time-barred.

A win could net Harry millions in damages, akin to his £12 million News Group settlement, plus apologies and capped legal costs of £5 million.

Yet defeat risks total dismissal, deepening Harry’s royal rift while validating his media intrusion grievances. Broader fallout may spur press reforms, echoing the Leveson Inquiry’s legacy.
