This is apparently why Prince Harry and Meghan Markle hold hands in public, but William and Kate don’t

It makes complete sense when you think about it

Prince Harry and Meghan Markle are undoubtedly the world’s most closely-watched couple, with people across the globe arguably paying more attention to the royal relationship than their own. Especially now that they're expecting - the Duke and Duchess of Sussex have everyone talking about them and their upcoming baby.

Even we have to admit that we can't draw our eyes away from their public displays of affection (they look so happy, always).

But while Harry and Meghan have no reservations when it comes to hand-holding in public, our other favourite Royal couple, Prince William and Kate Middleton, seem to avoid affection altogether.

While it would make sense to think that their choice to avoid PDA is down to Royal protocol, there are no official rules against them making physical contact in public.

So, why is there such a marked difference between the two royal couples?

Body language expert, Robert Kermode, explained to the Daily Mail why the couple choose not to hold hands in public. It’s all because of the Queen.

Queen Elizabeth and Prince Philip, despite being married for almost 70 years, are rarely seen holding hands, their personal choice setting a precedent that the rest of the royal family are following.

'Because Meghan isn't a member of the Royal Family, she wasn't attending the Invictus Games for business reasons,' The Sun reports. And Prince Harry, although on official duties, was technically not representing the Royals so the couple were free to be publicly affectionate.

There are of course times when Prince William and Kate Middleton do surprise us with a public display of affection, their most famous being on the day of the Royal wedding where they gave the cheering crowd outside of Buckingham Palace TWO kisses from the balcony.

Let's just revisit that for a second.

The cutest.

Since Prince Harry and Meghan Markle tied the knot, things appear to have been significantly more affectionate between William and Kate when they've been out and about in the public domain.

They were spotted looking very sweet at a recent royal visit, and were caught briefly holding hands at Princess Eugenie's wedding.

Maybe Harry and Meghan's PDAs are rubbing off on the couple?
