PRINCESS Anne will visit Huntingdon on Wednesday, March 31 to formally open a new �250,000 extension of the headquarters of St John Ambulance.

The princess, who is Commandant-in-Chief of St John Ambulance, will be given a tour of the Mayfield Road building in Hartford.

Pat Harrington, assistant commissioner of special events for St John Ambulance, said: "We are very pleased and honoured that the Princess Royal will be visiting us."

The team moved all Cambridgeshire personnel into the purpose-built headquarters in July last year.
