'Turn up the pressure on Heather..

DIVORCE row Heather Mills claims to have a secret bombshell tape of Sir Paul saying he hopes she'll commit SUICIDE.

In a phone call to his daughter Stella, Macca allegedly says: "If we turn up the pressure on Heather, with a bit of luck she will top herself and then we won't have to pay her a penny."

The astonishing recording is said to have been made last year while the ex-Beatle was in the farmhouse of his posh estate in Peasmarsh, East Sussex.

And it is expected to form a major part of Mucca's case for a multi-million-pound divorce settlement.

A close source said: "Her legal team feel that if the tape is genuine it is one of the most damning things Paul has ever said."

Sir Paul's spokesman and Heather's PR Michele Elyzabeth refused to comment.

Heather's new lawyer Matthew Higdon of firm M Law said he had been unable to contact his client and would not comment.

But the source said: "When Heather found out what was said on the tape, she was very distressed. It was such a terrible thing to say, whether it was meant or not.

"Heather was very shocked and hurt and has discussed the tape several times with her sister Fiona.

"She knows that she and Stella never saw eye to eye but she never expected anything like this."

Just last month it was revealed that Heather-believed to want a £50 million lump sum-allegedly had a secret recording of Sir Paul mocking her amputated leg.

He is said to call her a "one-legged bitch" on a cassette of his calls, handed to her by a third party. It is not known who made the secret recordings-and there is no suggestion Heather was behind them. But the 39-year-old is expected to add them to her "box of evidence" which was made before the couple's split in May 2006 and is securely stashed in a bank vault.

It already includes, she says, a tape of Sir Paul admitting he hit his first wife Linda.

Their relationship is widely believed to have been one of the most loving in showbiz, before Linda died from breast cancer in 1998.

A witness who claims to have heard the recording said: "It was extraordinary. Heather and Paul were shouting. He can be heard confessing he hit Linda 'once or twice'."

Heather, who has a four-year-old daughter Beatrice with Sir Paul, also claims to have video tapes she made with him discussing their problems. She says they shed a different light on their four-year marriage.

And she has threatened to make them public unless the 65-year-old star admits fault for the breakdown of their relationship.

Previously Heather has stated he pushed her over a coffee table, another time into a bath and that he boozed too much.

Details of the new recording emerged after Heather appointed a new set of lawyers this week.

Last month top-notch law firm Mishcon de Reya parted with her following her TV rants against Sir Paul.

Heather raged on camera that accusations against her-that she was a whore, a gold digger, fantasist and a liar-had driven her close to the edge.

She ranted: "I've stayed quiet for my daughter. We've had death threats, I've been close to suicide.

Silence

"I've had worse threats than a paedophile or a murderer and I've done nothing but charity work for 20 years."

But Heather, who was ditched by her PR guru Phil Hall after her tirade on GMTV in October, insists she was not dumped by the law company. Sir Paul is represented by Fiona Shackleton and supported by fashion designer Stella, 36.

He will not be drawn on Heather's allegations, telling aides he wants to keep a dignified silence and resolve the dispute in court.

In the meantime the estranged couple are sharing access to Beatrice, with Sir Paul getting her at Christmas.

The divorce case is set for February.
