TV star Judy Finnigan has claimed Heather Mills suffers from “borderline personality disorder” just like the late Princess Diana.

Finnigan says Mills – currently locked in a bitter divorce battle with Sir Paul McCartney – should seek help to deal with her condition.

She says in a new magazine interview, “I think Heather's a textbook case... it is quite a serious condition, characterised by paranoia, fantasy and delusions.

"I'll tell you who else suffered from that - Princess Diana. When Heather compared herself to Diana, I think there was some truth in it, though not in the way she meant. I think she really needs help."
