Meghan Markle and Prince Harry's sweet nod to Princess Anne with their birthday video of Archie

Princess Anne is patron of Save The Children

Meghan Markle and Prince Harry delighted fans by sharing a sweet video of their son Archie in honour of his first birthday. The couple chose to release the footage through the Save the Children charity, to help bring much-needed support to millions of children during the pandemic. Their decision would have resonated with one member of the royal family in particular – Princess Anne. The Princess Royal became Patron of Save The Children in 2016, having served as President since 1970. She has spent a significant amount of time visiting Save the Children’s projects, both in the UK and overseas, including Bangladesh, Sierra Leone, South Africa, Mozambique Ethiopia, and Bosnia and Herzegovina.

Self-deprecatingly calling herself a "boring old fuddy-duddy," Anne said: "I don't think this younger generation probably understands what I was doing in the past and it's often true, isn't it? You don't necessarily look at the previous generation and say: 'Oh, you did that?' Or: 'You went there?'" The Princess went on: "Nowadays, they're much more looking for: 'Oh, let's do it a new way' and I'm already at the stage, 'Please do not reinvent that particular wheel. We've been there, done that. Some of these things don't work. You may need to go back to basics.'"
