In Norfolk, visitors were at Sandringham, as they have throughout the Easter break, to walk their dogs and enjoy the fresh air.

Joining them today were what seemed like just an equal number of reporters, photographers and police officers.

Barriers and police sealed off the main entrance for vehicles to allow people to lay flowers at the gates.

A few dozen bouquets lay by the wrought iron gate, one accompanied by a card for the Queen.

In the distance, a flag was flying at half-mast on Sandringham House.

Westminster Abbey will toll its tenor bell once every minute, 99 times, from 6pm (BST) this evening in tribute to the Duke of Edinburgh.

Prince Philip, who died aged 99, had a long association with the Abbey, where he was married to the Queen on 20 November 1947.

His last attendance at an Abbey service was in 2017, when he accompanied the Queen to the Commonwealth Day Service.

A bank of photographers and cameramen are lined-up around the growing number of tributes.

Buckingham Palace has asked people not to gather due to coronavirus restrictions, but many people are already down here.

Rhea Varma, from Pimlico, pulls up on her bike to lay flowers and a note saying Rest in Peace Duke.

“It’s just super sad."

To her, the duke was “the kind of stability that’s so old-fashioned it’s difficult to comprehend. He was a rock who brought integrity.”

Parliament is currently on recess for the Easter break.

The House of Commons was due to return on Tuesday, but will instead now sit on Monday at 2:30pm to pay tribute to Prince Philip.

The House of Lords was scheduled to return to work on Monday. That day will also now pay tribute to him.

A period of mourning following the death of the Duke of Edinburgh will see planned government announcements and ministerial appearances cancelled.

With England’s lockdown easing on Monday, Prime Minister Boris Johnson had planned to celebrate with a pint in a pub garden – but this will now be postponed.

Prince Philip dedicated his life to supporting his wife and was a permanent fixture by her side on royal engagements over the decades.

Despite their familiarity to millions around the world, public comments about one another were rare.

But in a speech to mark their golden wedding anniversary in 1997 the Queen made it clear how dearly important her husband was.

She described him as "someone who doesn't take easily to compliments, but he has, quite simply, been my strength and stay all these years, and I and his whole family, in this and many other countries, owe him a debt greater than he would ever claim or we shall ever know".

Philip was a dedicated and skilled sportsman who used sport as an escape from the duties of royal life.

He was a skilled, competitive sailor and his activities on the water helped establish Cowes as a centre of yachting excellence.

He was also a very good cricketer.

The famous Australian batsman, Don Bradman, once said, only half-jokingly, that he should have been considered by the England selectors.

Philip’s great love was polo, which he played until he was in his fifties, enduring his fair share of falls.

When arthritis made it difficult to swing a mallet he took up carriage driving, popular in Europe but not in the UK.

He helped establish it, writing much of the rulebook which governs the sport in this country.

As the Queen's consort, the Duke of Edinburgh is expected to be given a ceremonial royal funeral rather than a state one, according to protocol.

State funerals are usually reserved for the sovereign.

His funeral is expected to take place at St George's Chapel in Windsor - although the long-held arrangements have been amended in light of the coronavirus pandemic.

Ceremonial funerals are also held for the heir to the throne and for members of the royal family who hold high military rank. The Queen Mother had a ceremonial funeral in 2002.

State funerals have, on rare occasions by order of the monarch and by a vote in Parliament providing the funds, been held for those other than sovereigns, including Lord Nelson and wartime Prime Minister Sir Winston Churchill.

Both can include a lying in state - as the Queen Mother's did, although Philip's will not - and a military procession.

The Duke of Edinburgh has made such a huge contribution to the success of the Queen’s reign.

The Queen and Prince Philip were quite different in terms of character – the Queen, quite cautious and reserved, whereas the duke was full of self confidence – but together the partnership really worked.

He in support, a role which he adapted to and adjusted to and found he was rather well-suited to - he was utterly loyal in his belief in the importance of the role that the Queen was fulfilling - and in his duty to support her.

It was the importance of the solidity of that relationship, of their marriage, that was so crucial to the success of her reign.

As a young boy Philip’s family were driven from Corfu, the place of his birth, and were living in exile in Europe.

In Paris, he lived in a house borrowed from a relative; but it was not destined to become a home.

In just one year, while he was at boarding school in Britain, the mental health of his mother, Princess Alice, deteriorated and she went into an asylum; his father, Prince Andrew, went off to Monte Carlo to live with his mistress; and his four sisters married and went to live in Germany.

In the space of 10 years he had gone from a prince of Greece to a wandering, homeless, and virtually penniless boy with no-one to care for him.

More former prime ministers have paid tribute to Prince Philip, including Boris Johnson's predecessor, Theresa May.

"The nation and the entire Commonwealth owe Prince Philip an extraordinary debt of gratitude for a distinguished life of service to the Queen, our country and so many around the world," she said in a tweet.

Another former Conservative prime minister, David Cameron, said the duke "showed true dedication to our country".

"He has been a huge part of our national life since long before most of us were born," he tweeted.

"It was an honour and privilege as prime minister to see up close what a powerful advocate the duke was for the causes he believed in."

And Sir John Major, who served as prime minister in the 1990s, said: "It is impossible to exaggerate the role that the Duke of Edinburgh has played in his lifetime of service to the monarchy and to the United Kingdom.

"A distinguished naval officer, he was - for over 70 years - the ballast to our Ship of State.

"Modest to the core, and hating any kind of fuss or bother, he epitomised the British spirit and remained true to himself right up to the very end."

Prince Philip, Duke of Edinburgh, won widespread respect for his steadfast and constant support of the Queen.

It was a desperately difficult role for anyone, let alone a man who had been used to naval command and who held strong views on a wide range of subjects.

Yet it was that very strength of character that enabled him to discharge his responsibilities so effectively, and provide such wholehearted support to his wife in her role as Queen.
