Prince Charles And Camilla's 'Blue Peter Moment' In Dar Es Salaam

The Prince of Wales and Duchess of Cornwall had a "Blue Peter moment" in Tanzania, as they raced each other to make pieces of jewellery.

They visited a charity workshop which employs disabled men and women in the country's capital, Dar es Salaam, and decided to have a go at making a couple of pieces.

Charles and Camilla sat side-by-side at a table to learn from Wonder Workshop staff how to make earrings and a necklace respectively.

The Duchess asked 28-year-old Neema Mohamedy, who sat beside her: "Are you going to show me what to do? I'm not normally very good at this."

As she was handed a leather lace to thread through a blue glass ring, she said: "This is a Blue Peter moment."

Wonder Workshop was set up by Briton Paul Joynson-Hicks, 40, after he kept seeing a group of polio victims begging near his office in Dar es Salaam in 2004.

After making some metal artwork himself, he thought the beggars would be able to do the same, despite their injuries, so he invited them into his workshop. Now the charity employs 33 disabled men and women who make art out of scrap metal, wood and glass.

Charles, who was given some tiny beads to thread through thin wire, said: "This is where I need my glasses."

Noticing her 62-year-old husband was in difficulty, Camilla, 64, offered him her glasses three times. "Do you want my specs?" she asked. The Prince laughed: "I'm not designed for this."

And when he was handed even smaller beads by his helper Otaigo Wairoma, 27, he snorted, then said: "That's not fair!"
