Tory peer Michelle Mone has announced she wants to build a sailing boat and travel the world with her new partner, the Scots-born millionaire Douglas Barrowman, after the couple put their French Riviera mansion on the market.

In an interview with a Sunday newspaper property supplement, Lady Mone revealed that she and Mr Barrowman, who currently share six homes, would “probably” sell one of their two superyachts.

She and Mr Barrowman are selling a £13 million, seven-bedroom villa overlooking Cap Ferrat, one of the most exclusive stretches of France’s Cote d’Azur. Yet she told The Sunday Times: “I am probably happiest when gazing at the 180-degree views from our terraces over the Bay of Villefrance-sur-Mer.”

Lady Mone added: “My dream is to build a sailing boat with Douglas - to our own design - and sail around the world. We have two superyachts and I don’t want to sound spoilt but this would be a great way of seeing the world together. We plan to sell our villa in the south of France and probably one of the yachts.”

The Conservative was best known as the front woman for the Ultimo lingerie brand she set up with her ex-husband, which she sold after it began racking up losses. She has made numerous claims to have had a successful solo business career although this cannot be verified through public documents.

The Herald earlier this year revealed Mr Barrowman, with whom Lady Mone moved in last year, had marketed previously legal employment benefit trusts or EBT tax avoidance schemes through one of the companies in his offshore empire based out of the Isle of Man.
