It’s been revealed that the Earl and Countess of Wessex will attend next week’s memorial service for Diana, Princess of Wales.

However, the latest update to the diary of royal engagements, released today by Buckingham Palace, is yet to confirm the appearance at the televised service of the Duchess of Cornwall. Nor is there any mention as yet of Princes Charles, William and Harry, albeit there is no doubt they will be at the event honouring Diana on the 10th anniversary of her death.

The late Princess enjoyed relatively good relations with Prince Edward, and the two even undertook a public engagement together following Diana’s official separation from the Prince of Wales.

In an unexpected move, the Princess – now very much seen as estranged from the Royal Family - joined her brother-in-law at a Commonwealth Day reception at Marlborough House in London in March 1993.

Onlookers noted how happy and relaxed Diana and Edward were together as the Prince deputised for the Queen, who’d pulled out of the event due to a bout of flu.
