THE Prince of Wales has extended his patronage of the Devon County Agricultural Association for the next five years. Prince Charles has been patron of the DCAA, which runs the Devon County Show in May, since 2002 when he succeeded The Queen, who had been patron for the previous 50 years. Mervyn Hosking, the secretary of the DCAA, said: ?We are honoured and delighted that His Royal Highness has agreed to extend his patronage for a further five years.?
