Party time at Tatler

The stock market may be taking a pounding but there was no sign of jitters at the party to celebrate Tatler's annual most-invited list.

Guests at the Orangery Kensington Palace spanned socialites such as Tara Palmer-Tomkinson and Jimmy Choo boss Tamara Mellon, Cartier boss and party co-host Arnaud Bamberger and literati including William Boyd.

Isaac Ferry, the 17-year-old second son of singer Bryan, is doing work experience on the magazine and tried not to be photographed with a drink in his hand. also present was Bond star Pierce Brosnan's son Sean, who two years ago survived a near-fatal car crash.

Grander guests at the pink-lit pavilion were en route to a party held by Lady Annabel Goldsmith in Richmond, others were heard to whisper they must not be late for "the Kashoggi's dinner".

According to Tatler editor Geordie Greig: "The most-invited list is the social radar of Britain, and the party is to celebrate those people who register on it." Greig claims he was besieged for invites from Hollywood but in the rarefied world of Tatler, movie stars are not the real celebrities.

The Chelsea girls were more interested in the three van Cutsem brothers, sons of Prince Charles's best friend, Norfolk landowner Hugh van Cutsem, and themselves members of Prince William's inner circle.

Tara Palmer Tomkinson made sure she left before the arrival of her ex, property developer Anton Bilton, who arrived an hour before his present squeeze, model Lisa B.
