Lady Louise Windsor dons a high-vis jacket as she mucks in at the Horse Show and takes an electric bike for a spin

Lady Louise Windsor was spotted mucking in at the Royal Windsor Horse Show this afternoon as her parents attended as spectators.

The 20-year-old royal, who is 16th-in-line to the throne, was pictured in a high-vis jacket, a branded gilet, and a badge marking her as an ‘official’ as she carried a pen and paper and walked around the grounds.

Lady Louise’s parents, the Duke and Duchess of Edinburgh, and her brother James, Earl of Wessex, attended the same event as spectators and appeared to be enjoying the show, – but it was a day of hard work for their daughter.

The Royal, who is not often seen in public, donned a trilby hat and glasses, and wore her hair in a low ponytail away from her face so she could concentrate.

On the bottom, she donned comfortable tracksuit bottoms and practical waterproof boots.

Her appearance comes after she did not attend the Easter Sunday Service with her family last month which was held at St George’s Chapel in Windsor – the second year in a row she missed the event.

The 20-year-old is currently studying English Literature at the University of St Andrews in Scotland, which is where Kate and William’s relationship blossomed.

According to the University’s website, both the week before and the week after Easter still count as term-time.

This period is followed by two weeks of revision, with exams beginning on Saturday 20th April.

It seems the young royal has taken a little time out of revision to fit in some shifts at the Royal Windsor Horse Show, which her family attends every year in Berkshire.

And this year, spirits are especially high as King Charles has attended the event following the news that his doctors are ‘positive’ about how his cancer treatment is progressing.

As Lady Louise Windsor works quietly behind the scenes, it has been claimed that there will be a special place in the royal family for her when the Prince of Wales eventually ascends the throne.

The Daily Mail’s Diary Editor, Richard Eden, has previously said: ‘In my opinion, another great service the couple could do for the country would be to encourage their children, Lady Louise and James, the Earl of Wessex, to become working royals when the time is right.
