Prince Philip the Duke of Edinburgh has visited Cornwall on a number of occasions – sometimes on his own and at other times accompanying a Queen. Following the news that the duke died earlier today, aged 99, the Packet looks back on some of those royal trips to the Duchy that his eldest son, Prince Charles, is duke of. One of the most recent occasions was in August 2014, when Prince Philip visited the Tregothnan Estate to look at how its tea is produced and packaged on site. He planted a tea bush and was introduced to the estate s bee colonies, before going on to plant an oak tree.
