Queen Elizabeth II's eight grandchildren held a 15-minute vigil at their grandmother's coffin.

Previously, King Charles III.

and Prince William visited the mourners queuing outside Westminster Hall.

At the request of her father King Charles III.

Both heir to the throne Prince William (40) and Prince Harry (38) wore military uniforms.

At previous ceremonies, unlike his brother, Harry, who served in Afghanistan, wore civilian clothes - he had to relinquish his military titles when he left the royal family.

Farewell to "Granny"

After Prince Andrew, who had to give up his official duties in the Royal Family after his involvement in an abuse scandal, was allowed to wear a uniform at a wake by the Queen's children, there was criticism – and Harry was finally allowed to wear a uniform as an exception.

The remaining granddaughters wore formal black attire.

William and Harry stood at the head and foot of the coffin.

Along the long sides and lined up were the children of Queen daughter Princess Anne, Zara Tindall and Peter Phillips, and Prince Andrew's daughters, Beatrice and Eugenie.

The Queen's youngest grandchildren, Lady Louise and Viscount Severn, Prince Edward's children, also attended the special farewell to their "grannie".

There was almost total silence around the coffin during the wake, although many Britons attended the grandchildren's performance after waiting hours in line at Westminster Hall.

Charles III

and Prince William surprise mourners

The rush to say goodbye to Queen Elizabeth II's coffin never stops.

Thousands of mourners waited several kilometers along the Thames in London to pay their respects to the Queen.

Authorities estimated the wait for those who queued on Saturday at more than 24 hours.

The closed coffin of the Queen is laid out in the Westminster Hall of the British Parliament until Monday morning before the state funeral for the Queen, who sat on the throne for 70 years.

The British King Charles III.

and Prince William paid a surprise visit to mourners in the kilometer-long queue outside Westminster Hall in London on Saturday.

Britain's new monarch and his son shook hands and chatted with waiting citizens on Lambeth Bridge, which spans the Thames. 

Before the funeral service for Elizabeth II and her funeral on Monday, hundreds of thousands of people are expected to say goodbye to the late Queen at the coffin this weekend.

Westminster Hall remains open to the public until 7:30 a.m. on Monday morning, with the monarch's coffin laid out in state.

The authorities expected another huge rush on Saturday and Sunday.

incident on Friday evening

An incident occurred late Friday night when a man attempted to touch the coffin.

The Metropolitan Police said the man had been arrested for violating the Public Order Act.

Previously, King Charles III.

and his siblings - also for a quarter of an hour - took over the wake at the coffin.

King Charles III, Princess Anne, Prince Andrew and Prince Edward positioned themselves around the coffin in the evening, all in uniform, clasped their hands and looked down.

Many other members of the Royal Family attended the wake from a podium on the edge of Westminster Hall in Parliament.

The wake was reportedly the only occasion at the celebrations that Prince Andrew was allowed to wear a uniform.

The Queen stripped her second eldest son of all military ranks earlier this year for his involvement in the abuse scandal surrounding the late US multi-millionaire Jeffrey Epstein.

At all other ceremonies he was dressed in civilian clothes.
