Harry and Meghan are said to have personally told their team last month that they would be losing their jobs after announcing their decision to step down as senior royals.
It is understood that one or two of those working for the pair would be given new roles elsewhere in the royal household but that most are now negotiating redundancy packages.
The reported decision comes after the duke and duchess’s Frogmore Cottage staff were set to be “redeployed” as the couple prepared to start a new life in Canada.
It is believed that the redundancies will be concluded by the time Harry and Meghan’s move to step down as senior royals are formally concluded, after their final official duties.
The Sussexes are now living in Canada with their baby son Archie Mountbatten-Windsor as they prepare to drop their HRH styles and quit the monarchy in favour of financial freedom.
