Anne with her husband Vice Admiral Sir Tim
Anne spent her milestone birthday at sea off the west coast of Scotland with her husband Vice Admiral Sir Tim Laurence.
Appearing in an ITV documentary in July ahead of his wife’s 70th birthday, Sir Tim revealed: "Our ideal break, if we have a break, is to go up to our boat on the west coast of Scotland and spend a few days sometimes getting wet and cold. I navigate. I know how to get from A to B. But she’s a better sailor of the boat, better at setting the sails."
The Princess notched up a remarkable 506 official engagements in 2019, making her the hardest-working member of the royal family after her brother the Prince of Wales.
Anne impressed royal fans this week as she visited her patronage Citizens Advice Harlow, wearing a personalised face mask, complete with her royal monogram and coronet.
