"In quiet periods employees are often redeployed elsewhere around the estate," the source told CNN after reports appeared in the British press on Friday and claimed that Harry and Meghan had let go of staff while preparing to settle in Canada.
"No employees have been released," the source confirmed.
CNN was told last week that the Duchess had been back in London for a few days, but new images in the British press indicate that she is still in Canada, suggesting that the plan has changed.
Questions have been raised about whether the couple intends to live together in the UK for an extended period of time, or whether they plan to settle in North America.
The couple eventually plans to split the time between Canada and the United Kingdom, but will be staying at Frogmore with the Queen's permission in the short term.
