Many of Sunday's front pages bear the words "My dear Papa" as they lead on Prince Charles's tribute to his father.
The Sunday Times - wrapped in striking portraits of the Queen and Prince Philip taken 56 years apart - describes the address as an "emotional farewell".
The paper says it is a sign that the Prince of Wales and his father had become reconciled after "years of distance".
And, according to the Times, it marked the moment that Charles stepped up as the most senior man in the Royal Family.
He is now set to assume an even more high-profile role, the paper says, as the Queen's right-hand-man, and King-in-waiting.
The Sunday Mirror says the Duke of Cambridge and Duke of Sussex will walk "shoulder to shoulder" during their grandfather's funeral procession.
A source tells the paper there is hope that, with the brothers "united in grief", "a corner may be turned" in their relationship.
The Sun on Sunday, also citing a Palace source, says Prince Charles is looking forward to a reunion with Prince Harry, in their first face-to-face meeting in more than a year.
The comments are perhaps evidence of what the New York Times describes as the "fevered speculation" set in motion, about whether the reunion can mend fences in the Royal Family.
The paper believes a new and uncertain chapter has been opened, in what it calls the turbulent life of the House of Windsor.
There is plenty of focus on the modified Land Rover - designed by Prince Philip - that will carry his coffin from the state entrance of Windsor Castle, to St George's Chapel.
The Sunday People says the idea began as a joke between the Duke and the Queen in the 1980s.
According to the Sun on Sunday, the notion became a reality in 2005, when the vehicle was commissioned.
The paper says it is an adapted Defender 130 Gun, made by a firm that typically modifies the vehicle for shooting parties.
The Sunday Mirror reports that special forces soldiers have been deployed to Northern Ireland to help deal with riots that have spread across the country.
The paper says a Special Reconnaissance Regiment team will help MI5 identify the ringleaders behind the violence - amid fears it could spark the return of deadly paramilitary attacks.
The Observer says the government is resisting growing calls for a special summit to be held in Dublin, aimed at calming tensions.
Senior sources tell the paper that suggestions by the Irish government have been met with "no enthusiasm" on the British side.
Many of the papers look ahead to the next stage of lockdown easing in England tomorrow - with particular focus on the pub trade.
Industry leaders warn the Sunday Telegraph that two-thirds of pubs will not reopen as they lack the outside space to serve customers.
Brewers are keen to stress to the Sunday Express that pubs have "led the way" in introducing safety measures to protect customers and staff.
And the Daily Star Sunday makes no attempt to hide its enthusiasm for what it has dubbed "Magic Monday".
It says temperatures are set to rise - sparking a "two-week long, 60 million pint booze-up".
