A new portrait of the Duke and Duchess of Cambridge has been revealed on Twitter. Leeds-based royal photographer Paul Ratcliffe, shared the picture which was featured on a Thank You card he received from Buckingham Palace on 24 May.

Kate and William sent the personal card to fans and well-wishers who had sent them messages of congratulations when they celebrated their fifth wedding anniversary on April 29. The photo on the front of the card, taken by royal photographer Chris Jelf, shows the young royals in the gardens at Kensington Palace.

In the picture, the ever-stylish Kate is wearing an Alberta Ferretti beige embroidered detail jacket matched with a white pleated skirt. The back of the card has a personal message which reads: "The Duke and Duchess of Cambridge were so touched that you took the trouble to write as you did on the occasion of their 5th Wedding Anniversary. It really was most thoughtful of you and Their Royal Highnesses send you their warmest thanks and best wishes."

The royals previously sent out similar thank you notes expressing their gratitude for the good wishes on the birth of their son Prince George.

A fan of the royals, Paul Ratcliffe, who has published two books of photography of the royal family, revealed he was not expecting the tweet to garner so much public interest.

"Who would have thought my twitter would go into melt-down after I received a thank you card from the Cambridges!! ," he said. "Still can't believe all the attention my tweet on a card I received from The Duke & Duchess of Cambridge received :-) Thanks to everyone!"
