Royal travel secrets: Princess Diana was once labelled a 'loose cannon' for this decision

Luckily, there were plenty of people in support of her.

Christina Lamb OBE, journalist and author of ‘Farewell Kabul’ went along to cover the tour and says it completely changed her opinion of Diana.

Though at first Christina was annoyed to have been forced to go along, as she was usually on the ground for war coverage, she said Diana showed unprecedented compassion.

In the documentary, she says: “Angola was still at war at that time, a really brutal civil war, and I have to say my impression of her completely changed because it was a difficult trip.
