The royal siblings – whose father is Prince Andrew – attended restaurauteur David Tang’s annual bash at his upmarket eaterie housed in The Dorchester hotel, where other guests included Kate Moss, Sir Tom Jones and former British prime minister Tony Blair.

The girls were also joined by their boyfriends, Dave Clark and Jack Brooksbank, and everyone seemed in good spirits as they left in the early hours of yesterday morning (05.04.13).

Last month, the sisters drove a Mini through the streets of Berlin as they launched a campaign promoting the UK.

Beatrice and Eugenie flew to the German capital to support the Great Campaign, a global initiative to attract visitors, business and students to Britain.

In a short speech before their trip in the Mini, she said: ”The Great Campaign is designed to showcase the very best that we have to offer.

”It is also a welcoming home for investors. We’re here to encourage more German businesses to join the thousands that are developing successful partnerships in Britain.”
