- The Duchess of Cambridge travelled to the pageant in a carriage with the Duchess of Cornwall and Prince Harry
- Trio smiled and waved at the crowds lining the route as the carriage drove to the televised military spectacle
- Royal family gathered on balcony on Buckingham Palace to watch spectacular RAF fly-past
- After ceremony Queen paid a 'private and quiet' visit to her husband Prince Philip, who is recovering from surgery
In many ways it was a very familiar Royal balcony tableau.
Prince William and Kate giggled and flirted. The Queen, striking in blue, acknowledged the spectacular fly-past with a beatific smile.
There was some good-natured tomfoolery from Prince Harry, who made his sister-in-law laugh with a tickling gesture. And there was even a mildly recalcitrant child, Prince Edward’s five-year-old son James, Viscount Severn, who couldn’t resist making faces.

But the glaring omission from yesterday’s line-up at the Queen’s official birthday celebrations was, of course, the Duke of Edinburgh, who is still recovering from abdominal surgery. Without his bolstering presence, the scene appeared incomplete.
No sooner had she dispensed her final wave, though, than Her Majesty was off to visit her husband in hospital.
But if the day belonged to the 87-year-old Monarch, all eyes were on the eight-months-pregnant Duchess of Cambridge, making her last public appearance before the birth of her first child.
Before the balcony appearance, Kate watched proudly as her husband took part in the traditional Trooping the Colour on horseback as Colonel of the Irish Guards.

Wearing a pale pink Alexander McQueen coat with pearl buttons and matching hat, she had travelled to the pageant in a carriage with the Duchess of Cornwall and Harry, smiling and waving at the crowds lining the route.
Other senior Royals also arrived in carriages before the Queen made her entrance, travelling with her cousin, the Duke of Kent, in a glass coach for the short journey from Buckingham Palace to Horse Guards Parade.
The Queen, dressed in a royal blue Angela Kelly coat and hat with a matching lace dress, took the salute as her family – including the Duke of York and his daughters Princesses Beatrice and Eugenie, and the Earl and Countess of Wessex with their daughter Lady Louise Mountbatten-Windsor – looked on.
After the parade ended, the Queen was cheered as she was driven back to Buckingham Palace, and the King’s Troop Royal Horse Artillery fired a 41-gun salute in Green Park.
It is thought to be only the third time that Philip has missed the event after not attending in 1962 and 1968 when he was away on royal tours.
She first took the royal salute in 1951 - when she deputised for her sick father, George VI - and has continued receiving the mark of respect every year except 1955 when there was a national rail strike.

Other royals watching included the Duke of York and his daughters Princesses Beatrice and Eugenie, and the Earl and Countess of Wessex with their daughter Lady Louise Mountbatten-Windsor.
Taking part in the ceremony on horseback are the Prince of Wales - who is Colonel of the Welsh Guards, the Princess Royal - who is Colonel of the Blues and Royals, and the Duke of Cambridge - who is Colonel of the Irish Guards.
More than 1,000 soldiers, horses and musicians are taking part in the parade known as 'Trooping the Color,' an annual ceremony marking the queen's official birthday.
The ceremony is also an important social occasion for the Guardsmen taking part and gives their wives, girlfriends, and relatives the chance to celebrate the achievements of the young men and enjoy the spectacle.
Many of the spectators in the stands overlooking the parade ground were dressed in morning suits or smart suits, while women wore dresses topped with hats and fascinators.
After the parade ended, the Queen was cheered by crowds gathered along the Mall as she was driven back to Buckingham Palace, where she watched an aerial display by the RAF.

The royals then gathered on the balcony at Buckingham Palace to watch the traditional RAF flypast.
Thousands of spectators crowded around the front of the palace and on The Mall, many cheering as a succession of planes roared overhead.
Among the featured 32 aircraft were 13 different types - from the famous Spitfire, Hurricane and Lancaster aircraft of the RAF Memorial Flight - to modern multi-role Typhoon fighters.

After the splendid ceremony, the Queen paid a visit to the Duke of Edinburgh, who is recovering from exploratory abdominal surgery at a London hospital.
The Queen, who changed into a pale blue suit, was unaccompanied as she made the visit 'quietly and privately', a Buckingham Palace spokeswoman said.
Philip also had a number of other visitors yesterday. He received a flurry of family visits during the day and at one point had the Prince of Wales and his wife the Duchess of Cornwall, the Duke of Cambridge and Prince Harry with him.
Earlier in the day his granddaughters Princesses Beatrice and Eugenie also made a trip to the hospital.
As Charles left the hospital, after a visit that lasted 35 minutes, he looked relaxed and smiled, and when asked by the waiting media how his father was, said "much better".

The heir to the throne arrived with Camilla around 15 minutes before his sons William and Harry.
The royal brothers stayed on after their father and stepmother left and spent around 40 minutes with their grandfather. They left without making any comment to a large crowd that had gathered outside the central London hospital.
As well as missing the Trooping the Colour ceremony today, Philip will also be unable to attend next week's events including the traditional Garter service at Windsor Castle and Royal Ascot.
The Duke is said to be progressing according to plans following his operation on June 7 and is expected to stay in hospital for around another week.
He is expected to spend two months convalescing after being discharged.
Philip was admitted to the London Clinic for the pre-arranged operation on June 6, following a garden party at the Palace that day.
The Colour that was paraded on Horse Guards this year is the flag of the 1st Battalion Welsh Guards.

Four of the five Foot Guards regiments of the Household Division - the Welsh Guards, Grenadier Guards, Scots Guards and the Coldstream Guards - were marching in the parade wearing bearskin hats and red tunics.
The Household Division Bands and Corps of Drums were also taking part, along with the King's Troop Royal Horse Artillery.
The ceremony originates from traditional battle preparations, when 'colors,' which refer to military flags, were carried down the rank to be seen by soldiers.
Although the Queen was born on 21 April and turned 87 this year, it has long been the tradition to celebrate the Sovereign's birthday publicly on a day in the summer, when good weather is more likely.
Trooping the Colour is carried out by fully trained and operational troops from the Household Division (Foot Guards and Household Cavalry) on Horse Guards Parade in Whitehall, watched by members of the Royal Family, invited guests and members of the public.

Royal Salutes have been fired at both Edinburgh and Stirling Castle to mark the Queen's official birthday.
Gunners from 105th Regiment Royal Artillery (Volunteers) fired the two 21-gun royal salutes at noon.
Meanwhile, 1st Battalion Scots Guards, in their familiar red tunics and bearskins, provided both castle guards.
It is the first time the battalion has mounted a guard at Stirling in more than 300 years.
The royal salutes took place as the Queen attended the Trooping the Colour parade at Horse Guards Parade in London's Whitehall.
Commanding officer of 105th Regiment Lieutenant Colonel James Cook said: 'As the Scottish and Ulster Gunners, we are honoured to be firing royal salutes at Edinburgh and Stirling Castles on the occasion of Her Majesty the Queen's official birthday.
'We are extremely privileged to have the General Officer Commanding Scotland, Major General Nick Eeles, as the reviewing officer at Stirling Castle; and the Deputy Commander Land Forces, Major General Ranald Munro, as the reviewing officer at Edinburgh Castle.

'It is also a great pleasure to have 1st Battalion Scots Guards provide the guard at both castles, and it is worth noting the last time the Scots Guards mounted a guard at Stirling Castle was 1685.
'In addition, the regiment has now been given the official authority to fire four royal salutes annually at Stirling Castle. These will usually be fired by the regiment's 212 (Highland) Battery.'
Music at Stirling Castle was provided by the Highland Band of the Royal Regiment of Scotland.
The royal salute at Edinburgh Castle was fired by 207 Battery, with music from the Lowland Band of The Royal Regiment of Scotland.
The carriage that transported the Queen was built in 1881 as a town coach for the Lord Mayor of London, it was purchased for King George V's coronation in 1911.
It has been used for most royal weddings since then, including by the Queen when she married Philip in 1947 when she was still Princess Elizabeth.
