Newspaper headlines: 'Reunited in sorrow' and 'Russian forces retreat'

Nearly all of Sunday's front pages focus on the Royal Family reuniting to mourn the death of the Queen.

Most of the front pages focus on the Prince and Princess of Wales and the Duke and Duchess of Sussex, as they read tributes left by mourners outside Windsor Castle on Saturday. The Sunday Times says the brothers "put months of bitter discord behind them" to jointly honour their grandmother's memory. The Sunday Telegraph's headline is "Reunited in sorrow". "Together for granny" is the The Sunday Express choice. It describes seeing the couples together again as a "powerful symbol of unity at a time of great loss".

Inside the papers there are also many pages dedicated to other members of the Royal Family, including Princess Anne and Princes Edward and Andrew, who spoke to well-wishers outside Balmoral. The Mail on Sunday says they "consoled" each other in public while reading messages left at the gates.

The proclamation of King Charles III was an "extraordinary ceremony", says The Observer. The Sunday Times believes the event demonstrates "the sturdy, ancient machinery of the British state" clicking seamlessly into gear for this "passage of power".

The paper describes the ceremony - which for the first time in its long history was televised - as "fascinating, moving and reassuring in equal measure". The Sun on Sunday reports that it may have been "shrouded in secrecy" before but this time the "pomp was laid bare in fascinating detail".

Some of the papers offer an assessment on the King's first few days in his new role.

The Prince and Princess of Wales and the Duke and Duchess of Sussex meeting crowds of mourners outside Windsor Castle on Saturday features on most of the front pages. The Sunday Telegraph says William and Harry put aside their differences to "honour" their grandmother. The Sunday Mirror sums up the occasion with the words "Reunited for Granny".

Tim Adams in The Observer writes that over the years many have expressed uncertainty about Charles becoming king, but he argues that over the past few days there's been a "rapid sea change in sentiment" towards the new monarch.

He writes that when speaking to people who had gathered for the Platinum Jubilee celebrations, only a few months ago, some had told him it might be "preferable to skip a generation" and fast-forward to William. But he says no-one who has travelled to gather in front of Buckingham Palace in the past week would admit to having ever held that opinion now.
