The duke blames the Press for Chelsy Davy dumping him after she decided that 'a royal life was not for her', the High Court was told today.
He claimed in his witness statement that 'whenever' he has been in a relationship, the woman 'is not just in a relationship with me but with the entire tabloid press' who try to 'ruin it'.
Harry and Zimbabwe-born Miss Davy, his first serious girlfriend, met in early 2004 and were in an 'on-off' relationship until mid-2010.
Harry alleges that the Daily Mirror must have used phone hacking when it followed up The Sun's story about the infamous time he dressed as a Nazi aged 20 at a fancy dress party in 2005.
The Mirror article alleged he had flirted with a 'stunning brunette' at the party and Miss Davy, then 19, was 'furious', rang him at his father's Highgrove home and gave Harry 'a tongue-lashing down the phone'.
