The Duke and Duchess of Cambridge walked the red carpet as they highlighted Africa's threatened wildlife at the UK premiere of African Cats.

William and Kate were dazzled by dozens of flashbulbs when they arrived for the screening of the nature documentary raising funds for the Duke's UK-based animal conservation charity Tusk Trust.

The royal couple, who celebrate their first wedding anniversary on Sunday, stepped from their chauffeur-driven car and walked the short distance to the BFI Southbank in London as banks of photographers shouted for their attention.

Kate was wearing a Matthew Williamson grey jacket and matching skirt, with three-quarter-length sleeves and coloured, beaded detail around the neck and sleeves, while William looked smart in a dark suit.

Mark Knopfler, lead singer of the group Dire Straits, was among the guests along with filmmaker Guy Ritchie and Dragons' Den judge Deborah Meaden, a patron of Tusk Trust.
