"Like you and many others, they are both part of the rich history of the British Red Cross, which is helping to ensure many people get the support they need during a crisis," Kate said.

Courtesy of the Middleton Family In 2018, Kate launched the Nursing Now campaign, aimed at raising the profile and status of nursing worldwide, so that nurses can make an even greater contribution at the heart of efforts to tackle rising burdens of disease. "This campaign means a lot to me personally. My great-grandmother and grandmother were both volunteer nurses,” she said in a speech. “They would have learned first-hand from working with the Voluntary Aid Detachment and the Red Cross about the care and compassion that sometimes only nurses can provide."
