The estranged wife of ex-Beatle Sir Paul McCartney could be set to receive a divorce settlement of about £70 million.

Heather Mills’s divorce deal – after four years of marriage – would easily eclipse the £48 million paid by insurance magnate John Charman to his former wife Beverley, making the largest in British legal history.

Heather’s currently appearing in Dancing With the Stars on BBC1 on Sunday afternoons.

The 39-year-old former model could receive a lump sum of £15 million, according to The Daily Mail, as well as an annual payment of about £3.5 million every year until the couple’s daughter Beatrice reaches 18.

The paper says: “The divorce settlement – which would be the largest in British legal history – will include a clause ensuring that neither party ever speaks publicly about what led to the breakdown of their marriage.”

It was also reported that Heather would not be given any of her former husband’s properties and that he would pick up the childcare costs for their daughter.

She lives on the seafront in an exclusive part of Hove, East Sussex. Sir Paul has a country estate in nearby Peasmarsh and property in London.

Sources for the estranged couple refused to comment on the progress of their divorce but did confirm that the financial details of a settlement have been agreed, the paper added, although the case remains listed for a five-day hearing before a family High Court judge next February.

Heather alluded to her divorcee status recently by saying she was ‘soon to be just Mills’.
