On 20 March 1974, Princess Anne was ambushed by an armed kidnapper as she travelled by car to Buckingham Palace.

The attack was thwarted by the bravery of a number of people, including her police bodyguard Inspector Jim Beaton, who was shot three times during the incident.

Ian Ball planned to abduct the young princess and hold her ransom. He was later prosecuted for Jim鈥檚 attempted murder, as well as other offences.

Five decades on, Inspector Beaton has been reflecting on that day.
