Prince Charles looked right at home, inspecting a haunch of wild boar and sampling luxury olive oils.
A farmer himself, and an advocate of organic food, he took special interest in the produce being sold at many of the stalls.

But, it looked rather more incongruous when Charles started sipping on a cup of "builder's tea".
The Prince normally has his tea without milk and with a spoonful of honey, but he ordered one with two sugars and as strong as you can make it from cafe-owner Maria Moruzzi.

No card for Charles, but lots of Valentine's gifts for Camilla
The Duchess of Cornwall was presented with armfuls of gifts from traders, as she toured Borough Market.
Florist Sharon Crane, 45, whose business opened today, gave her first bunch of flowers to the Duchess for free.

Afterwards she said: "I told her 'I'm giving you a bouquet of flowers in case your husband forgets' and she said she was hoping to get some."
She was also presented with a massive chocolate heart, decorated with the words "with love from Borough Market".

But it seems Charles is having a rather less romantic Valentine's day. When asked by David Ruane, a worker from a nearby pub, if he'd received a card, he rolled his eyes and said: "No, I don't think so."

Borough Market's largest trading area, Three Crown Square, reopens today after being closed for over three years. The section of the market was closed In 2009, due to works being carried out by Network Rail.
Children from St Mary Magdalene Church of England Primary School are among those selling the fruits - and veg - of their labours at Borough Market today.
Here are some pictures of them planting their seeds earlier in the year.
