A multi-millionaire property developer has been found guilty of murdering his escort girlfriend.

Peter Morgan, 54, killed Georgina Symonds at her bungalow in Llanmartin, south Wales, after hearing of her plans to fleece him, leave him and work for other men, the court heard.

They were also told the father-of-two paid Ms Symonds, a former burlesque dancer, up to £10,000 per month and allowed her to live rent-free at the £300,000 property.

Newport Crown Court heard that Ms Symonds had a series of intimate pictures of Morgan which she threatened to show to his wife and daughters.

Morgan - who is worth an estimated £20 million - admitted killing the 25-year-old but denied murder on the grounds of diminished responsibility and loss of control.

The court heard that on January 12, the day of the murder, Morgan drove to Ms Symonds' house and strangled her with twine he had prepared earlier.

He then packaged her body and hid it in an outbuilding near the farmhouse where his wife and two daughters lived.

He confessed to police hours later, chillingly handing them keys and telling them "you will need those keys, she is locked in an outbuilding".

During the trial, Morgan told the court Ms Symonds had blackmailed "a few" previous clients, including taking the £70,000 life savings of one elderly man.

At the time of her death Ms Symonds had £119,870 in her bank account.

In November 2015 Ms Symonds told Morgan that she planned to blackmail one of her clients for £2,000 per month.

Later the same month, Morgan installed a £45 listening device he had bought online, disguised as a white ply adapter, in the bungalow, the court heard.

He called the device on the evening of January 10 and overheard Ms Symonds talking to her lover, during which she said Morgan would transfer the bungalow into her name, and then she would leave him and "do him over".

A jury at Newport Crown Court found Morgan guilty of Ms Symonds' murder.

Morgan will be sentenced later on Wednesday.
