The Queen is now lying in state in Westminster Hall.

Built in 1097, Westminster Hall has played a significant role in British history for centuries.

King Charles III addressed members of Parliament and peers there on Monday, but it has also hosted the trials of Charles I and Guy Fawkes, Henry VIII's coronation banquet, and speeches by well-known figures such as Nelson Mandela, French President Charles de Gaulle, Pope Benedict, and US President Barack Obama.

The last member of the Royal Family to lie in state at Westminster was the Queen Mother in 2002, when more than 200,000 people queued to file past her coffin and pay their respects.

But it is not only royals who have lain in state in Westminster Hall.

The same honour was extended to former Prime Minister Winston Churchill following his death in 1965 and to the victims of the R101 airship disaster of 1930.

As the service is over, members of the public will soon be able to pay their respects to the late Queen.

From 17:00 BST, they will be allowed to enter Westminster Hall.

The Queen will lie in state until 06:30 BST on Monday, the day of her funeral, which has been declared a bank holiday across the UK.

During the lying-in-state period, Westminster Hall will be open for 24 hours a day.

The Queen's closed coffin will rest on a raised platform, known as a catafalque, and guarded in a continuous vigil by soldiers from units that serve the Royal Household.

The coffin will be draped with the Royal Standard, and topped with the Imperial State Crown, orb and sceptre.

King Charles III and Camilla, Queen Consort, leave Westminster Hall shortly after the service finishes.

They are driven through the Palace of Westminster's gates to shouts of "God Save the King" from some of the assembled crowd.

Archbishop Welby offers a blessing to close the short service in Westminster Hall.

Soon afterwards, a sword is tapped firmly on the ground, twice, marking the start of the vigil.

The Queen's coffin is now officially under watch on all sides, before members of the public are allowed to visit a little later to file past the late monarch.

Reporting from the queue on Lambeth Bridge

After many hours of waiting, the queue to see the Queen lying in state is on the move, but very slowly.

We are being called through the barriers in groups of 20 at a time, as we begin the walk across Lambeth Bridge before snaking back around towards Westminster Hall.

A warden has told the crowd: "Just to manage expectations, there will be some waiting. I will be at the front of the queue and I will be moving slowly."

A few moments from Westminster Hall, those at the front of the queue waiting to see the Queen lying in state have begun to cross Lambeth Bridge.

After crossing the river, they will have to walk north to Westminster Hall - where they will be allowed to view the coffin from 17:00.

Following the Archbishop of Canterbury, we hear from the Dean of Westminster, David Hoyle.

He offer further prayers - including the Lord’s Prayer, which is recited by all those present in Westminster Hall.

The choir proceeds to sing a classical motet by Anglican composer Edward Bairstow.

At the entry of the Queen’s coffin, the choir of Westminster Abbey and the choir of His Majesty’s Chapel Royal sang Psalm 139.

Archbishop of Canterbury Justin Welby says the opening prayer and a recites a passage from the Gospel of John.

A 20-minute service is now being held in Westminster Hall for members of the Royal Family.

Other officials are also attending, including members of the House of Commons and House of Lords, and members of the UK’s devolved parliaments.

Slowly, and very carefully, the pall bearers carry the Queen's coffin into the Palace of Westminster.

They do so having removed their bearskin hats.

Eight young men from the Grenadier Guards have been entrusted with the task.

It's a moment they've practised in great detail.

The crowds right outside Westminster Hall were mostly silent as the cortege passed.

Many had been waiting hours for a short glimpse of the late monarch's coffin.

But once the band stopped - just a few moments ago - they broke into applause, with some whistling and calling, as shots were heard from the gun salute.

The clapping faded away as military calls were made, ahead of the coffin being moved off its carriage.

Queen Elizabeth II’s coffin has reached the Palace of Westminster - the home of the UK Parliament - after a solemn procession through the streets from Buckingham Palace.

The gathered crowds fell silent as it arrived in Parliament Square at 3pm.

Next, the bearer party will carry her coffin to a catafalque (raised wooden platform) in the oldest part of the estate, Westminster Hall.

Members of the Royal Family will process into the hall themselves, in order to attend a short service conducted by the Archbishop of Canterbury supported by the Dean of Westminster.

The gun carriage has travelled down Parliament Street and is now heading down the east side of Parliament Square, where there’s a Guard of Honour made up of members of the Army, Royal Navy and Royal Air Force, and a band of the Royal Marines playing muffled drums.

The Queen’s coffin will enter the Palace of Westminster via New Palace Yard.

Under the constant steady beat of the drum, the cortege enters the last part of the journey towards Westminster.

They pass the Cenotaph, which was first unveiled in 1920 in the aftermath of the Great War.

It is where the Queen came year after year in November to remember the dead.

Members of the Royal Family salute the Cenotaph as they walk past.
