Heather MillsHeather Mills is reportedly planning on suing her former lawyers for misrepresentation in the early part of her divorce proceedings.

Heather is said to have run up £2million in legal bills during the first 18 months of her divorce battle before the firm Mischon De Reya dismissed her as a client following her unauthorised television interviews in November.

The firm has threatened legal action over the debt - which Heather says she can not pay until after her financial settlement from estranged husband Paul McCartney is agreed - but now Heather is said to be planning to countersue for “bad representation”, claiming they failed in their negotiations.

The divorce case will be heard at the High Court in London next week, with Heather representing herself in court.
