Prince Andrew is reportedly set to appear alongside the Queen next month during a remembrance service for Prince Philip.
He is expected to attend the ceremony at Westminster Abbey on March, 29.
The event will come only days after the Duke of York is due to give his witness statement to US lawyers in the sex abuse case.
Andrew, 61, failed to quash a bid to bring it back to court earlier in the year, on the basis of a financial settlement his accuser, Virginia Roberts, signed with Jeffrey Epstein.
The event is one of three work dates that the 95-year-old Queen has next month, following a health scare in October.
Prince Harry has not yet confirmed whether he will fly back to the UK from California, to join the other royals.
The Duke of Sussex is suing the government for not allowing him to pay for his and his family’s own police protection.
Yesterday, Buckingham Palace said the Queen will “be resuming her normal duties” immediately.
This includes audiences, credentials and privy council meetings, but some maybe shifted to virtual audiences.
The Sun also report that today she may hold her first direct call with PM Boris Johnson since mid-December.
Alongside Philip’s remembrance service, the Queen will attend two other work dates next month.
The Palace announced one will be a Diplomatic Reception that she will host at Windsor Castle on March 2, only eight days before Prince Andrew’s planned deposition.
She will also attend a Commonwealth Service at Westminster Abbey on March 14 before returning just over a fortnight later for the remembrance service.
The service will remember her husband who died last April aged 99.
Before Saturday’s reception at Sandringham, where she marked 70 years on the throne, the Queen had gone 52 days without an official engagement.
Ingrid Seward, editor-in-chief of Majesty Magazine, said: “One of the Queen’s Ladies-in-Waiting once told me that the Queen told her, ‘If I stop then I drop’.
“The Queen won’t be happy to sit down in front of the TV for the rest of her days. It is the way she has always lived her life.”
