See which royal has worked the hardest so far in 2018

The Queen steps out for so many high-profile engagements that there's no denying she's still very committed to her service, while her grandchildren the Duke and Duchess of Cambridge are always furthering their causes with public appearances. Even Meghan Markle hit the ground running following her engagement to Prince Harry, as the couple toured dozens of organizations around the UK in the walkup to their royal wedding. But as the numbers for the most hardworking royal of 2018 have been released by the Court Circular, you'll be surprised to find that none of the above topped the list - in fact, it was Princess Anne who logged the most days of service this year with a whopping 75!

The Princess Royal, Her Majesty's only daughter, held the top spot in 2017 as well. This year's tally runs from Jan. 1 to May 22, and sees her brothers following her lead in the rankings, with the Earl of Wessex clocking 59 days and the Prince of Wales stepping out for 53.

The circular's newest addition, the Duchess of Sussex, stepped out for her first official engagement as a royal on Tuesday (May 22) at a garden party celebrating her father-in-law Prince Charles' 70th birthday at Buckingham Palace. Prince Harry's new wife had previously joined her fiancé on 16 days of engagements, from Nottingham and Birmingham to Cardiff, Commonwealth Day and finally ANZAC Day, though they're not officially counted on her record.

Rounding out the royals are the Duke of Cambridge with 33 days, the Duke of York with 31, the Duchess of Cornwall with 30 and an impressive 26 for the 92-year-old Queen, who is still a force, no doubt! And finally, Duchess Kate was out for 22 days in 2018, having gone on maternity leave in March ahead of the birth of her third child, Prince Louis.

Despite being retired, Prince Philip still made his way onto the list following his attendance at the royal wedding. The 96-year-old had undergone hip surgery just a few weeks before Meghan and Harry's big day, but luckily was in great form as he watched his grandson tie the knot.
