Sophie is a working member of the Royal Family which means she will often attend royal engagements and events.
She also has a number of her own interests in charities and organisations and is patron to more than 80 patronages.
The royal couple also have their own foundation, The Wessex Youth Trust, which was established in 1999.
Speaking to Express.co.uk, body language expert Judi James explained how the couple’s body language has changed over the years.

Announcing their engagement in early 1999, the couple posed for photos at St James’s Palace.
Judi explained: “Unlike the fireworks between his brothers and their wives, Edward’s marriage to Sophie began with a huge amount of press and public interest before they slowly slid under the radar to get on with their lives and their relationship and start their family.
“Their trick to disappearing from view was similar to the technique used by William and Kate as well as generations of royals before them, which was to retain a level of blandness so that they could get on with their duties but without attracting the kind of soap opera interest that would leave fans begging for more.
“Their PDAs as a young engaged couple were negligible and they posed looking pleasant but formal. There was none of the brittle, edgy-looking incongruence of Charles and Diana’s engagement shoots or the sexy flirting between Andrew and Fergie during theirs.”

The expert added that the couple looked “more practical and less romantic”, because they were dressed in suits for their engagement snap.
She explained: “Dressed in suits that looked right for a day at the office, their poses looked more professional too. Take Sophie’s hand out of Edward’s arm and they could be business colleagues posing together for a corporate photo.
“Edward’s pose had a slight wariness to it.
“His smile wasn’t totally convincing as it didn’t round his cheeks, making it look performed rather than natural and his only sign of affection was the way his torso leant slightly towards hers as though feeding off her strength.”
However according to Judi, Sophie’s smile looked authentic due to her rounded cheeks and some “eye-crinkling”.
“Her signals of confidence were stronger than Edward’s. Her left arm performed the ring reveal but the right was tucked behind her back suggesting she is hiding or concealing some of her inner thoughts and emotions here.”
Since marriage, the couple will regularly attend events together but will also undertake separate royal duties and also make appearances separately.
Throughout the pandemic, the couple have individually taken to virtual chats, speaking to a huge variety of different people.
Judi explained that their relationship has grown over the years, explaining that what “looked to be missing in their earlier photos does seem to have grown over the years”.
She added: “Edward and Sophie are much more comfortable looking close now and often pose like the loving couple they didn’t appear to be initially. Sophie seems to have given her husband the trick of relaxing and showing happiness and joy in public.
“All their recent appearances, including the very tricky one when they had the job of providing a human buffer between William and Harry at their last public outing together, have shown them looking actively happy and delighted with each other.
“Maturity and parenthood seems to suit them, as does the way the power-balance has come down firmly in Sophie’s favour, with Edward apparently happy to take a bit of a back seat.”
