Two matching portraits of princess Diana and Prince Charles by pop art icon Andy Warhol have gone on display for the first time since 1982, ahead of being sold.

The paintings show Charles in naval attire against a blue background. His first wife Diana wears a formal dress and is pictured against a pink background.

They were made using synthetic polymer and silkscreen ink on canvas and marked the couple’s wedding in 1981.

A set of cufflinks featuring an 18-c gold finish has been made using parts from Prince Charles’s Aston Martin to raise money for charity.

Pistons removed from the car when the prince decided to convert the vehicle to make it more eco-friendly have been transformed into cufflinks.

A total of 200 cufflinks were made by TMB ArtMetal, and they were designed to resemble the DB6 and the car’s iconic wheel ‘spinners’.

The Prince of Wales opened the new global headquarters of British fashion house Burberry, at Horseferry House in London: totalling 160,000 sq ft over eight floors, houses over 800 employees and comprises cutting edge show rooms, design studios, modern contemporary office space and photo studios together with the exterior architectural features of the original 1930s building.

Britain’s Prince Charles has beaten off competition from US President Barack Obama to be named the world’s best dressed man by Esquire magazine.

“He is perfectly turned out in a double-breasted suit. Admirably, the prince keeps his wardrobe in appropriate style: we’re told he has a room laid out like a tailor’s shop,” the men’s magazine said.

Prince Charles, 60, keeps it simple and has worn suits by Saville Row tailors Gieves and Hawkes, complete with pocket handkerchief and silk tie, for years. Esquire said he was “always incredibly well dressed”.
