Young Jensen Moore struck up such a conversation with the Duchess of Cornwall at this year's Sandringham Flower Show that she labelled him a 'chatterbox' - as he and his brother presented her and Prince Charles with flowers.

Samantha Moore, 33, from King's Lynn, brought her two children Carson, eight, and Jensen, three, to the popular summer event and got them to meet the royal couple for the second year in succession.

Mrs Moore said: 'We come every year. It's a nice way to start off the summer holidays and the boys like to meet the Duchess and the Prince.

'They've always got such a lot of time for them. They've always made a fuss of them. He [Prince Charles] said we were familiar faces. She [Camilla] called Jensen a chatterbox because he wouldn't stop talking.

'It was a lovely interaction. They're really child-friendly. They make a beeline for children and really make an effort.'

The Duchess of Cambridge also took the time to visit the National Osteoporosis Society tent at the Sandringham Flower Show.

The Duchess of Cornwall was made president of the National Osteoporosis Society in 2001.

Jill Fysh, chairman of the King's Lynn and District branch of the National Osteoporosis Society, said: 'The flower show is good for everyone, bringing in local people and people from outside into West Norfolk.

'It's a very good charity money making opportunity. We get a great deal of money from Sandringham but the other thing it's good for is raising awareness.'

Mrs Fysh talked to Camilla about the research the society does and the campaign to renew its contract for a DEXA scanner in West Norfolk.

Mrs Fysh added: 'She's very supportive. She does lots of work around the country for the charity and she was very knowledgeable about the condition.'

Also attending was Geraldine Calver, 75, from Bradwell near Great Yarmouth.

'We've been quite impressed,' she said.

'The stalls are quite interesting and coffee and tea is not that expensive. It is a good opportunity to meet Prince Charles. It is nice to see them in the flesh as we have never had that opportunity.'

She added that the attendance at the event showed how popular the monarchy is, adding: 'I think we'd be lost without it.'

Others hoping to talk to the royal couple ahead of their tour around the marquees and stalls included Marion and Ron Guthrie, who are from Derbyshire but have a holiday home in Heacham, near Hunstanton.

'We come here regularly and the show is a special reason to come,' said Mrs Guthrie.

'It would be nice to see them. I think they make a lovely couple.

'I think the monarchy is very important. They're not all perfect, but no-one is. If we lose the monarchy, we lose our identity.'
