The Children's Heart Federation charity has said it is "horrified" by the bill run up by the Royal Brompton Hospital, in its courtroom battle with another NHS body.
The hospital had challenged a consultation by the Joint Committee of Primary Care Trusts, which had proposed closing the children's heart unit at the Royal Brompton.
The charity has urged other hospitals not "to waste this level of money on further legal action".
