Police have warned Heather Mills-McCartney that they have received intelligence of a threat to her safety.

Officers spoke to the 38-year-old and her estranged husband, Sir Paul McCartney, aged 64, on Thursday about the "non-specific threat" from the Merseyside area.

Ms Mills-McCartney was also told the names of the people who had made the threat, Sussex Police said. According to reports, she has been given a panic alarm which allows her to contact Sussex Police headquarters directly. However, officers have said there is "no imminent risk" to the model.

The former model and Sir Paul, who have a threeyearold daughter, Beatrice, announced in May that they were ending their four-year marriage.

Ms Mills- McCartney revealed last month that she had received death threats in the wake of her split from Sir Paul.

The former model said she feared for her personal safety. "We have had a few death threats, which was scary," she said during a visit to Brussels to campaign against the fur trade.

Ms Mills-McCartney said her personal trainer Ben Amigoni, who she emphasised was "not my lover", was also helping to protect her.
