Royal family LIVE: Charles and Camilla attend garden party on tense day for Prince William

The Duchess of Edinburgh has been in Geneva this week. 

She addressed the World Health Assembly for the first time, underlining the importance of addressing preventable blindness - one of her most cherished causes. 

Her Royal Highness said more than one billion people are living with preventable or treatable sight loss "not through any lack of solutions, but through a lack of sustained, prioritised action."

She said: "The value of vision is just not a moral argument but an economic argument. The case for investment is more than compelling. Every dollar invested in eye health in low- and middle-income countries generates an estimated twenty-eight dollars in economic returns.”   

"Eye health accounts for up to ten per cent of patient consultations in many low- and middle-income countries yet receives less than one per cent of national health budgets. That gap is not sustainable. And it is not justifiable."

Princess Charlotte has received some sad news ahead of her annual summer plans. 

The young royal, 11, often attends the Wimbledon tennis championships with her mother, the Princess of Wales. 

But the occasion won't be the same this year - read our story to find out why.
