It’s understood William, 41, and Harry, 39, sat on opposite sides of St Mary’s Church for the ceremony, separated by fellow mourners and the church aisle. “They were sat two or three rows back from the front, not at the back, but they were on opposite sides of the aisle,” a mourner said. “And then there were family members on the rest of the seats between them, so maybe that is something that was arranged.”

A source said: “A lot of people were taking the chance to speak to them. They were only about five yards from each other, it was virtually back to back. When we left the reception they were both still there, but as we were on a walk we saw Harry driven off in a black Range Rover.”
