Meghan, Duchess of Sussex has joined the Queen for an official engagement for the first time without her husband as the pair visited Cheshire.
The Queen smiled as she and Markle appeared to have a lively, upbeat conversation with each other.

There was one moment when Meghan appeared a little unsure who should get in the vehicle first, but hardly a serious issue.
She added: "The Queen was the happiest I've seen her in a long time".
It's protocol for The Queen to enter the vehicle first, but the monarch seemed happy to allow Meghan to enter before her.
Meghan Markle is probably the most talked about woman in the world, from her powerful fashion influence to her transformation from Hollywood actress to full-on royal since assuming a Duchess title. For the Duchess, this will have been on the royal train in the morning, before they embarked on the day of joint engagements.
Meghan has no doubt learned the royal etiquette rules from watching the royal family over the past few months. 'Showing people the ropes is a high priority for the Queen'. The unveiling of the 1.86 billion pound project was followed by a performance from local school children.
