Sotheby’s chairman Lord Dalmeny, 51, announces engagement to art director Harriet Clapham

Sotheby’s boss Lord Dalmeny has announced his engagement to his art director girlfriend Harriet Clapham – who is twenty years his junior. 

Harry Dalmeny, 51, only son and heir of the 7th Earl of Rosebery — and great-grandson of the 5th Earl who famously achieved his three ambitions of owning a winner of the Derby, marrying an heiress and becoming Prime Minister — shared the news on his private Instagram page.

According to Tatler, he posted a snap as he posed next to his fiancée in the gardens of Cliveden House, writing: ‘So delighted @harrietclapham said yes. Cliveden, your Fountain of Love did the trick.’

Often seen hobnobbing with the likes of Damien Hirst and sculptor Sir Anish Kapoor, Harriet, 31, is fast becoming an influential figure in the art world.  

Meanwhile Harry has four daughters and a son by his marriage to Caroline Daglish, from whom he parted five years ago, before romancing with former model Martha Sitwell.

It was first reported that the pair were dating in September 2020, when a friend told the DailyMail’s Richard Eden: ‘They’re very serious about each other.’

While a wedding date and location are yet to be announced, the event could take place at their home of Dalmeny House, which sits in rolling parkland west of Edinburgh. 

Scottish property developer’s daughter Harriet is a graduate of Sotheby’s Art Institute and has worked at the Gagosian Gallery in Mayfair.

Harriet now runs her own art advisory, specialising in ‘Post-War and Contemporary with an interest in Old Masters’ and is Founding Co-Chair of the Young Ambassadors at the National Portrait Gallery.

To celebrate her turning 31, Harry threw her a party at his family’s stately home, Dalmeny House, on the Firth of Forth in Scotland, which she described as ‘the most perfect birthday weekend’. 

Lord Dalmeny is chairman of auction house Sotheby’s and has connections to the royal family: in 2013, Lord Dalmeny rode in the Queen’s carriage at Royal Ascot.

He has lent his talent to charity and political fundraising auctions, including a British Film Institute gala attended by guests including Hugh Grant, Olivia Colman, Gemma Arterton, Danny Boyle, and Dame Joan Collins.

He was married to Caroline until 2014. The couple share four daughters and a son, including triplets Lavinia, Celeste and model Delphi, who recently graced the cover of society bible Tatler.

After his divorce, Lord Damleny entered into a relationship with effervescent former model Martha Sitwell, although the pair parted ways in 2019.

Now his daughter Delphi is poised to make a splash on the modelling scene. She was recently signed to Storm.
