Heather Mills will appeal later against the publication of the ruling in her £24.3m divorce settlement with former Beatle Sir Paul McCartney.

Former model Ms Mills said she was taking the step because details contained in the ruling could affect the security of her daughter Beatrice.

There is a stay in publication of the ruling until the appeal is heard.

A High Court judge determined the final figure after the couple failed to reach an agreement in court last month.

Ms Mills said: "I'm not appealing against the judgment because it's not worth it.

"I'm appealing against the publication of it because it has so many details of me and my daughter in it."

Ms Mills will appeal against the publication of the ruling on Tuesday morning.

Following the ruling, Ms Mills will receive £14m for herself and £2.5m to buy a house in London.

Sir Paul will pay for Beatrice's nanny and school fees, and give the four-year-old £35,000 a year. The judge awarded a lump sum of £16.5m and assets of £7.8m.

The settlement equated to £17,000 for every day of the couple's marriage.

The judge found the total value of Sir Paul's assets was about £400m. Ms Mills had sought £125m and been offered £15.8m.

Sir Paul, 65, and Ms Mills, 40, got married in 2002, but they split four years later, blaming media intrusion into their private lives.
