'Harry and Meghan are axing 15 staff and closing their Buckingham Palace office.
It is the surest sign yet that the couple and their son Archie are unlikely ever to return to the UK to live.
While one or two may be absorbed back into the royal household, most are now negotiating redundancy packages.
They are the latest casualties of Harry and Meghan's bombshell decision to move to North America and make their fortunes outside the Royal Family.
Last night Buckingham Palace said it did not comment on staffing matters but it is understood senior royals, including the Queen, Prince Charles and Prince William are aware of the office closure and redundancies.
A source told the Mail: 'Given their decision to step back, an office at Buckingham Palace is no longer needed. While the details are still being finalised and efforts are being made to redeploy people within the royal household, unfortunately there will be some redundancies.'
Among those to lose their jobs are the couple's newly appointed private secretary, Fiona Mcilwham – although she is on secondment from the Foreign and Commonwealth Office and is likely to be found in a role in Whitehall – and their hugely experienced communications chief Sara Latham.'
