A spokesman for Princess Anne's daughter confirmed: "They haven’t made any plans for their honeymoon yet.
"They will grab a holiday when they can – it's always last minute for them because of their busy schedules.
"When they were looking at wedding dates it was never an issue. They always knew it would be business as usual on the Monday after the wedding."
