The prince shook hands with 21-year-old actor Cameron Hancock, who is playing the panto's own Prince Charming.

The visit came a day after Prince Harry and Meghan Markle formally announced their engagement, in what has been billed as a real fairytale romance.

The Duchess of Cornwall has expressed her delight over Prince Harry's engagement to her soon-to-be stepdaughter-in-law Meghan Markle saying today 'America's loss is our gain'.

Fifth in line to the throne Harry has been dating the actress - who found fame in the US legal drama Suits - since the summer of last year.

Their 16-month whirlwind romance blossomed when they met through mutual friends in London, and the pair have been almost inseparable in recent months.

She tweeted from Stoke: 'Ah, sweet: asked about her new step-daughter-in-law #Meghan Markle today, the Duchess of Cornwall said: 'She's a star'. ' English also reported that Camilla was presented with an engagement card by a young girl.

She thanked her and assured her 'I'll make sure they get it.'Charles and Camilla were visiting the Potteries Museum to see a project to create a free online bank of pre-1900 watercolours from around the world, and catch a glimpse of recently-uncovered priceless Iron Age relics.

Miss Markle will most probably become HRH the Duchess of Sussex, if Harry is made the Duke of Sussex by the Queen on the morning of his wedding.

The pair were secretly engaged earlier this month, and Harry took Miss Markle to meet his grandmother the Queen for tea at Buckingham Palace in October.

They were also shown the First Day Vase, thrown by Josiah Wedgwood in 1769 to mark his founding of the Etruria manufactory, and recently secured for the public and future generations after £485,200 was raised for its purchase.

Afterwards, the royal party split up, as the Duchess headed across town to Stoke City FC stadium where, as patron of the National Literacy Trust, she was meeting more than 200 schoolchildren taking part in reading activities.

The couple will live together in Harry's current home, Nottingham Cottage at Kensington Palace, and Miss Markle will become an HRH and a senior royal.

She is expected to become a duchess - just like Kate Middleton did when she became the Duchess of Cambridge after saying her vows in 2011.

We’ve long become accustomed to the sight of fabulously wealthy and famous older men dating younger women, but when the age gap reaches more than 30 years, you have to wonder what the women can be thinking.
