Royals and Beckham attend Chelsea Flower Show

Don, not usually a fan of show gardens, said the chance to celebrate the dog-owner bond had won him over.

The garden will not be judged and will not stay. After Chelsea, it will find a permanent home at Battersea Dogs & Cats Home.

Along with Beckham and Blanchett, Dame Joanna Lumley and actor David Tennant were among those getting a preview of the world-famous event, along with BBC presenter Zoe Ball.
