Queen Camilla is "planning" to represent King Charles at five major events as the monarch continues cancer treatment.
A royal commentator claimed that Prince William, 41, will "welcome" the Queen's help in carrying out royal duties.
Camilla has taken on several duties for the King recently and will also lead the Royal Family at a Commonwealth Day service at Westminster Abbey on Monday.
She was also the most senior royal at a memorial service for King Constantine of Greece at Windsor Castle last week after William pulled out at the last minute.
Provisional plans are said to have been made for Camilla to represent the royals at the Chelsea Flower Show in May, as well as at four events in June.
These include the D-Day 80th anniversary commemorations, Garter Day, Royal Ascot and Trooping the Colour.
Today, Prince William visited the Oval cricket ground to celebrate an Earthshot Prize winner's new contract supplying sustainable packaging for use in sporting venues.
Royal commentator Michael Cole has claimed the Prince of Wales "won't worry about who does what in the Royal Family".
He continued to tell The Mail that William would not be jealous of Camilla's more prominent role, and would be "only too glad to see the responsibility for keeping the royal show on the road shared out between a suddenly reduced number of available working royals".
Queen Camilla has taken a short break following her long stint of royal duties recently.
Prince William has also reduced commitments while looking after Kate and their three children Prince George, Princess Charlotte and Prince Louis following his wife's abdominal surgery.
This year has seen a sudden shortage of frontline royals.
