Queen Elizabeth's Platinum Jubilee celebrations

Not everyone was enjoying the big occasion, as the latest pictures from the palace balcony show.

The overbearing noise of the 70 aircraft passing over Buckingham Palace proved too much for the young prince, who covered his ears and appeared to be letting out a scream.

The youngest child of the Duke and Duchess of Cambridge, who is 4 years old, was also seen looking fed up and pulling faces during the six-minute flypast staged by the Royal Air Force (RAF).

Nevertheless, his great-grandmother, mother, grandfather and sister do not appear to be remotely bothered by Prince Louis' refusal to maintain protocol, as they smile and chat to each other.

French President Emmanuel Macron has recorded a video message in English for the Queen, who he described as a "constant presence" and a "source of wisdom."

With the French and European Union flags in the background, Macron extended his "most sincere" congratulations on behalf of France to the British monarch on her Platinum Jubilee.

In a statement posted on social media Thursday, Macron said the Queen is "our friend, our close ally, our example of service to others."

"To celebrate you today is to celebrate the sincere and deep friendship that unites our two countries and your dedication to serving it," he said in the statement which was accompanied by French subtitles. 

The Queen, he said, is the "golden thread" that has bound the UK and France during her 70-year reign, during which his country "has relied on very few constants" on an international level. 

He continued: "Your first toast to one of my predecessors, René Coty, reminded us that 'trust and understanding should endure forever.' Your words were matched by a lifetime of devotion to our alliance."

"This year, the seventieth of your reign, we celebrate your achievements. We are grateful for your courage and we share the respect and love that the British people and Commonwealth have always shown you," he added.

The royal family gathered on the balcony at Buckingham Palace to watch the 70-aircraft flypast soar above central London.

Crowds of flag-waving royal-watchers gathered below as the Queen, wearing sunglasses, watched on flanked by her family. To her right stood her eldest son Prince Charles, together with his wife the Duchess of Cornwall. Meanwhile, on her left were the Duke and Duchess of Cambridge with their three children, Princes George and Louis and Princess Charlotte.

Also present are the Queen's children Edward and Anne, as well as a number of other relatives. The Sussexes, who were at the ceremony at Horse Guards Parade earlier but not seen, are not joining the royals on the balcony as the Queen decided last month that only royals carrying out official duties will be included.

Seventy aircraft, including the iconic Red Arrows and historic Battle of Britain Memorial Flight, put on the spectacular air show over London to mark the occasion.

Among the aircraft taking to the skies were Spitfires, Chinooks, Pumas and Apaches, some of which flew in formation marking out the number 70.

The King's Troop Horse Artillery has fired an 82 gun-salute in Hyde Park moments before the Royal Family appeared on the balcony at Buckingham Palace.

The Queen has emerged onto the Buckingham Palace balcony once more. This time she's joined by more family members for an appearance in front of thousands of roaring well-wishers who have been allowed to stream down The Mall towards the palace.

Alongside the Queen are three of her children, Charles, Edward and Anne, Prince William and Catherine and their children, as well as a number of other relatives.

Australia will host a series of celebrations this week to mark the Queen’s Platinum Jubilee.

More than 80 iconic landmarks and buildings across the country will be illuminated in royal purple, including the Sydney Harbour Bridge and Government House.

Canberra will hold an official event to light up the Australian Platinum Jubilee Beacon on the shore of the Australian capital’s Lake Burley Griffin. 

Over in Sydney, a seven-minute light show will be displayed on Thursday night to recognize the seven decades of the Queen’s reign.

"The Vivid Sydney '7 Minutes for 7 Decades' includes synchronized lighting of the Sydney Harbour Bridge, Luna Park, buildings around Circular Quay and Sydney Harbour Ferries in royal purple," tourism minister Stuart Ayres said in a statement.

Aircraft from the Australian Air Force's No.100 Squadron and Central Flying School will also conduct a flypast and aerial display over Aspen Island in Canberra.

Australia retains the British monarch as its head of state, though the monarchy has very little actual power in Australia – Queen Elizabeth’s role is almost entirely symbolic.

US Secretary of State Antony Blinken said on Thursday that the Queen's "unprecedented 70 years of service to the United Kingdom are an inspiration to Americans."

Blinken called the jubilee a "historic and joyous occasion," and sent his "heartfelt wishes for peace, prosperity, and good health to Her Majesty and all the people across the United Kingdom."

Former US President Barack Obama has recorded a heartfelt video message in which he said the Queen reminded him of his grandmother.

Wearing a suit and tie, Obama recalled his personal memories of meeting the Queen. The clip, broadcast on the BBC, lasts for one minute and 39 seconds.

He said: "When you are President of the United States you meet a lot of remarkable people and you try, under all circumstances, to maintain your composure. But that’s harder than you think when you are visiting Her Majesty.

"Before I took office Michelle and I hadn’t been to too many palaces so we weren’t sure what to expect on our first trip to Buckingham. But we shouldn't have been worried. 

"Certainly I can say that getting to know her was one of the great privileges of my years in office and I learned so much from seeing the example she set for all of us who had the privilege to serve.

"Your Majesty, it would be an understatement to say the world has changed a bit in the seven decades since you first came to power but your character never has. 

"Your steadfast stewardship of one of our most important democracies has made the world safer and more prosperous through war and peace, times of adversity and times of prosperity. 

"Your life has been a gift, not just to the United Kingdom, but to the world and it is with gratitude for your leadership and the kindness that you’ve shown me and my family that I say may the light of your crown continue to reign supreme."

The Queen has appeared on the balcony of Buckingham Palace to receive a salute as soldiers and officers return from Horse Guards Parade following the conclusion of the Trooping the Colour ceremony.

Dressed in an Angela Kelly ensemble and matching hat, she is watching the troops march past with a walking stick in hand. She is accompanied by her cousin, the Duke of Kent.

The monarch has opted to wear a dusky dove blue Charmelaine wool dress embellished with pearl and diamante trim around the neckline and cascading down the front of the coat. It's the same outfit she was photographed in for a new official portrait released by Buckingham Palace on Wednesday.

She is also wearing the Guards’ Badge.

The Duke of Kent is Colonel of The Scots Guards and is wearing a Scots Guards Tunic and Forage Cap with Garter Sash, adorned with numerous medals and decorations.
