HE has been wearing their shirts for 40 years – but today Prince Charles got to see how they are made during a visit to the Turnbull & Asser factory in Quedgeley.

HRH was shown around the site by two of the company’s longest serving employees – twin sisters Kath Cope and Bette Elton, who have nearly 100 years service between them.

The prince was shown the step-by-step process by which the shirts are made – and even had a go at sewing and making a button-hole.

At the end of the tour HRH was presented with a Sea Island Quality small blue and white check shirt.

On receiving the shirt Prince Charles thanked the workers and said: "I can’t believe I have been wearing the same shirt for 40 years. Is it time for a change, I don’t think so."

The company started making shirts for the prince in January 1973 and was granted a Royal Warrant for shirtmaking in 1980.

The royal visit was organised to mark the factory’s tenth anniversary.

Earlier in the day, the prince officially opened Uley Community Stores and Post Office, which was saved from closure by a local campaign.
