Camilla Al Fayed has bought a controlling share in Issa.

Daniella - who owns a 49 per cent stake in the brand - said: "The investment will help to grow the business and take it to the next level.

"I looked at a lot of investors, and Camilla came with the best fit. She has the infrastructure behind her, she's well connected, and she will open a lot of doors."

The duchess wore two Issa dress on her and Prince William's recent tour of Canada and North America, which the pair arrived back in Britain from this morning (11.07.11).

Princesses Beatrice and Eugenie have also been known to wear creations by Daniella and have been spotted at her London Fashion Week shows, while celebrities including Keira Knightley and Madonna have also been drawn to the clothing.
