Prince George has joined Queen Elizabeth II and members of the Royal Family on the balcony of Buckingham Palace for an RAF flypast to mark the Queen’s official birthday.
It was Prince George’s first balcony appearance, which traditionally follows the Trooping the Colour.
It is also the first time Queen Elizabeth has been seen at her birthday celebrations with her heir and heirs apparent.
More than 1,000 soldiers took part in the traditional display of army drill, music and horsemanship.
Twenty three-month old Prince George waved as the Red Arrows took part in a flypast that was largely reduced because of poor weather.
Queen Elizabeth and Duke of Edinburgh earlier travelled by carriage from Buckingham Palace to Horse Guards Parade where the parade took place.
Kate Middleton, meanwhile, made her first public appearance since she left hospital following the birth of Princess Charlotte.
Prince George was earlier pictured in a palace window, from where he appeared to be enjoying the pageantry.
There was no sign of Princess Charlotte but other guests at the event included UK’s PM David Cameron and his wife Samantha.
It is the 63rd time Queen Elizabeth has attended a birthday parade, a record unmatched by any monarch.
Joined by other senior royals, the Queen inspected 1,100 soldiers of the Household Division at Horse Guards Parade.
Earlier, the Prince of Wales, who is Colonel of the Welsh Guards; the Princess Royal, Colonel of the Blues and Royals; and the Duke of Cambridge, Colonel of the Irish Guards, rode on horseback in the procession to Horse Guards.
Kate Middleton, the Duchess of Cornwall and Prince Harry, meanwhile, travelled together to the ceremony in a horse-drawn carriage.
The Duke of York rode in a carriage with his daughters Princesses Beatrice and Eugenie, and the Duke of Kent and the Duke and Duchess of Gloucester were in the final coach.
The Earl and Countess of Wessex are away representing the Queen at the wedding of Prince Carl Philip of Sweden to former reality star Sofia Hellqvist.
The procession was accompanied by a Sovereign’s Escort of the Household Cavalry, made up of Life Guards and Blues and Royals, in their silver and gold breastplates and plumed helmets.
The Color paraded on Horse Guards this year was the flag of the 1st Battalion Welsh Guards.
The Prince of Wales Company, 1st Battalion Welsh Guards, trooped the Queen’s Color presented to them by the monarch at Windsor Castle in April.
The Household Division Bands and Corps of Drums also took part, as are the King’s Troop Royal Horse Artillery who, following the parade, will fire a 41-gun salute in Green Park to mark the Queen’s official birthday.
Kate Middleton made her last public appearance before the birth of her first child when she joined thousands of well-wishers to celebrate Queen Elizabeth’s official birthday at the Trooping the Color parade today.
Wearing a pale pink Alexander McQueen coat and matching hat, the Duchess of Cambridge, who is eight months pregnant, travelled to the pageant in a carriage with the Duchess of Cornwall and Prince Harry.
Kate Middelton smiled and waved at the crowds lining the route as the carriage drove to the televised military spectacle which is held every year at Horse Guards Parade in London’s Whitehall.
But it would appear the chilly weather was a bit too cold for the royal family, and they covered their laps with blue blankets.
Queen Elizabeth II celebrated her birthday with traditional pomp and circumstance – but without her husband by her side.
Prince Philip remains in the hospital, recovering from exploratory abdominal surgery.
Instead the Queen invited her cousin, the Duke of Kent, to join her in her glass coach for the short journey from Buckingham Palace along The Mall.
It is thought to be only the third time that Prince 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 deputized for her sick father, King George VI – and has continued receiving the mark of respect every year except 1955 when there was a national rail strike.

The Queen, dressed in a royal blue Angela Kelly coat and hat with a matching lace dress, looked on under cloudy skies which parted now and then to reveal the sun.
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.
The Queen took the royal salute as members of the royal family looked on.
Taking part in the ceremony on horseback are the Prince Charles – who is Colonel of the Welsh Guards, the Princess Royal – who is Colonel of the Blues and Royals, and Prince William – 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.
Following the parade, the King’s Troop Royal Horse Artillery fired a 41-gun salute in Green Park to mark the Queen’s official birthday.
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.
The Red Arrows completed the flypast – leaving a trail of red, white and blue smoke which swept across the sky behind them.
After the splendid ceremony, the Queen paid a visit to her husband, the Duke of Edinburgh, who is recovering from exploratory abdominal surgery at a London hospital.
Prince Philip appeared to be in good spirits as he attended the annual Trooping the Colour ceremony in honor of Queen Elizabeth’s official birthday.
The Duke of Edinburgh, who has resumed official duties after recovering from a bladder infection, attended the parade in London with the Queen.
Thousands of people watched the Prince of Wales and the Duke of Cambridge ride to the ceremony at Horse Guards Parade.
The military event came as the Queen’s Birthday Honours list was published.
Queen Elizabeth II and Prince Philip rode in a glass coach down the Mall to the ceremony. They were due to travel in Queen Victoria’s 1842 ivory-mounted phaeton carriage but this was changed due to the “unpredictable nature of the weather”, a Buckingham Palace spokesman said.
The coach, built in 1881, was first used by the Queen and Duke on their wedding day when they travelled from Westminster Abbey to the palace on 20 November 1947.
The Duke of Cambridge, who is Colonel of the Irish Guards and the Prince of Wales, who is Colonel of the Welsh Guards, were joined on horseback by the Princess Royal, Colonel of the Blues and Royals, and the Duke of Kent, Colonel of the Scots Guards.

The Duchess of Cambridge, Prince Harry and the Duchess of Cornwall travelled in a horse drawn carriage.
The parade was Prince Charles’ first public appearance since being awarded the highest rank in all three military services by the Queen.
The prince becomes a Field Marshal, Admiral of the Fleet and Marshal of the Royal Air Force. His appointment to the honorary five-star ranks recognizes his support for the Queen as Commander-in-Chief.
Also honored in the Birthday Honours list are actor and director Kenneth Branagh who has been knighted, ex-Olympic minister Tessa Jowell is made a Dame while Take That singer Gary Barlow is made an OBE.
Soul singer Omar receives an MBE for services to music, under his full name Omar Lye Fook, and Oscar-winning actress Kate Winslet becomes a CBE.
Thousands of people, including friends and family of those taking part, watched the precision marching by hundreds of Guardsmen.
Queen Elizabeth II, wearing her Brigade of Guards brooch, took the royal salute as senior members of the royal family looked on.
After the parade, thousands of well-wishers swarmed down the Mall to get into position in front of Buckingham Palace to see the royal family gather on the balcony for the flypast.
The Colour being paraded on Horse Guards this year is the flag of the 1st Battalion Coldstream Guards.
More than 1,600 officers and soldiers took part in the display.
More than 240 horses were be on parade, with 290 musicians who marched and played as one.
The traditional display of pomp and pageantry originated from traditional preparations of battle.
Colours, or flags, were carried or “trooped” down the rank so that it could be seen and recognized by the soldiers.
In the 18th century, guards from the royal palaces assembled daily on Horse Guards to “troop the colors”, and in 1748 it was announced that the parade would also mark the Queen’s official birthday.
The Queen’s actual birthday was on 21 April, when she turned 86.
During her reign, Queen Elizabeth II, who has recently celebrated her Diamond Jubilee, has attended Trooping the Colour every year except in 1955, when it was cancelled because of the national rail strike.
