This is the first photo taken by Louis that has been shared on royal social media channels as he follows in the footsteps of his mother, who has been an enthusiastic photographer.

At the weekend, Catherine called for a “rebalance” in society to allow people to prioritise their physical and mental health.

She is gradually returning to work after completing her cancer treatment – and launched a new stage in her early years education project encouraging more empathy and kindness.

“At times, it can feel like the world is filled with mistrust and misunderstanding, leaving many people feeling isolated and vulnerable during difficult times,” she wrote in her charity’s report.

She brought a message of support for those currently undergoing cancer treatment when last month she visited the Royal Marsden Hospital in west London, where she had been a patient.

This latest photograph is another indication of her continuing support, ahead of World Cancer Day, and how much she seems to have been motivated to help others by her own experience of ill health.
