Another new photograph of Queen Camilla has been released by Buckingham Palace today to mark her 78th birthday. Just hours after a picture of Her Majesty leaning on a garden gate at her home in Wiltshire was released, the Royal Family’s official Instagram account released a new photo of Camilla reading The Grey Wolf by Louise Penny.

The photograph is believed to have been taken in the garden of The Queen’s Ray Mill home, where she is believed to spend her quiet time away from royal duty. The Royal Family Instagram account captioned the photograph: “Thank you for the wonderful well wishes on Her Majesty’s 78th birthday today!”

It is believed Camilla will be spending her special day privately today.

This is the second portrait released by Buckingham Palace today, with the first one showing Camilla in her garden leaning on a gate.

In both pictures, Her Majesty is wearing a striking tropical rainforest print dress by Fiona Clare, which features wildlife motifs and a bold leafy pattern.

She is also beaming at the camera as she enjoys a sunny day at her private abode.

So far today, Camilla has been sent a number of birthday wishes from royal fans.
