THE Duke of Edinburgh, whose death was announced yesterday at the age of 99, was the longest-serving consort in British history. He was defined by his relationship with the Queen and relinquished the naval career he loved to support his wife in her royal role.

Over the years, he carried out more than 22,000 solo engagements and gave more than 5400 speeches, as well as taking part in thousands of other engagements with the Queen and committing himself to innumerable obligations behind the scenes.

The duke had a profound effect on the development of the British monarchy and was a moderniser of The Firm. In private, he was head of the family. To the public, he was the irascible figure who spoke his mind despite the consequences and was famed for his outrageous gaffes.

He once warned a group of Scottish students in China that they would become “slitty-eyed”.

In a Glasgow factory, he pointed to a fusebox of loose wires and remarked that it looked like it had been installed by an “Indian”.

The duke served in the Royal Navy during the Second World War. As a younger man he was a good shot, a first-class polo player, accomplished sailor, enthusiastic cricketer and international four-in-hand carriage driver.

When he turned 90, he was still associated with more than 780 charities. He was the oldest serving partner of a reigning monarch and finally retired from public duties in 2017, when he was 96.

Prince Philip of Greece and Denmark was born on the island of Corfu on June 10, 1921, to Prince Andrew of Greece and Princess Alice of Battenberg. His early years were marked by upheaval after his family went into exile following a military coup in Greece which overthrew his uncle, King Constantine I. George V, the Queen’s grandfather, ordered the Royal Navy cruiser HMS Calypso to evacuate the family and Philip was carried to safety in a cot made from an orange box in December 1922, aged just 18 months. His childhood lacked stability and he moved between relatives in France and Britain. His parents split up and he rarely saw either of them, with his mother, who suffered from mental illness, spending time in an asylum.

After a year at a school in Germany, he eventually went to Gordonstoun School in Morayshire. Philip later joined the Navy and, while a cadet, caught the eye of the 13-year-old Princess Elizabeth – a distant cousin – when she visited the naval college in Dartmouth with her parents, the King and Queen.

During the Second World War, the Duke saw active service from the Indian Ocean to the Mediterranean, and by 1945 was in Tokyo Bay as the Japanese surrendered. He was mentioned in despatches for his service on battleship HMS Valiant in 1941.

Then in 1947 he married Elizabeth in Westminster Abbey. He renounced his Greek title and became a naturalised British subject, and was made the Duke of Edinburgh by the King.

The duke and the princess had the first of their four children, Prince Charles, now the Prince of Wales, in 1948 and then Princess Anne, now the Princess Royal, in 1950.

They initially enjoyed a simple married life during stays on the island of Malta where Philip was stationed with the Navy. But their marital bliss changed forever when George VI died on February 6, 1952, and Princess Elizabeth became Queen.

Philip, whose naval career had come to an end, had to define a new role for himself as his wife took to her duties as head of state. He accompanied the Queen around the world on Commonwealth tours and state visits and across the UK.

He also undertook thousands of solo royal engagements, becoming involved with hundreds of organisations, often as a hands-on president. The duke set about modernising Buckingham Palace after being told to keep out of the Queen’s official duties, and reorganised the Balmoral and Sandringham estates, as well as becoming ranger of Windsor Great Park. “I tried to find useful things to do,” he said about starting a footman training programme at the Palace.

In 1956, he set up The Duke of Edinburgh’s Award – inspired by his time at the boarding school Gordonstoun and his mentor and headmaster, Dr Kurt Hahn. It has become one of the country’s best-known youth self-improvement schemes, with millions across the globe gaining their bronze, silver and gold awards.

The duke took a great interest in scientific and technological research and development, as well as the conservation of nature. After a gap of 10 years, the Queen and Philip welcomed two more children – Prince Andrew, now the Duke of York, in 1960, and Prince Edward, now the Earl of Wessex, in 1964. The duke was depicted as a tough but caring father.

An accomplished sportsman, he played polo regularly until 1971 and then took up four-in-hand carriage driving, representing Britain at several European and world championships. He also loved to shoot game. A qualified pilot, he gained his RAF wings in 1953, helicopter wings in 1956 and private pilot’s licence in 1959. His love of the sea never waned, and he competed regularly at Cowes Regatta.

The duke witnessed first-hand the troubles faced by the Windsors in the 1990s, from the scandal surrounding Sarah, Duchess of York – who was caught having her toes sucked by her financial adviser – to the fallout of Charles and Diana’s War of the Waleses.

When Diana, Princess of Wales, died suddenly in a car crash in Paris in 1997, Philip joined Charles, Princes William and Harry, and Diana’s brother, Earl Spencer, in the solemn procession behind her funeral cortege.

The same year, the Queen paid a moving tribute to the duke on their golden wedding anniversary.

THE duke helped the Queen through the deaths of both her mother and sister in the Golden Jubilee year of 2002, and was at her side in lockdown during the coronavirus pandemic.

He enjoyed good health throughout much of his life, recovering from a blocked coronary artery in 2011 and a bladder infection in 2012 – the latter leading him to miss the majority of the Queen’s Diamond Jubilee celebrations – and a hip replacement operation in 2018.

He was fit and active and continued to take part in fast-paced, dangerous carriage-driving events, competing at international level until the age of 85, but still riding non-competitively in later years.

When he was 97, he miraculously escaped unscathed when the Land Rover he was driving was involved in a serious crash with a car carrying a mother and a baby. He was spotted driving without a seatbelt just 48 hours later. Three weeks later, his days driving on public roads were over when he decided to voluntarily surrender his licence.

When he turned 90 in June 2011 he insisted there be no fuss, but the Queen bestowed on him a new title – Lord High Admiral, titular head of the Royal Navy. In May 2017, the Palace revealed that the duke had decided to soon retire from public duties. He took a typically irreverent view of his own retirement on the day it was announced, telling a guest who said he was sorry he was standing down: “Well, I can’t stand up much longer.”

He officially retired on August 2, 2017. In November 2017, the Queen and the duke marked their 70th wedding anniversary.

Even as he stepped back from public life, it was clear the duke’s behind-the-scenes support of his wife was unending. Philip’s first-ever private secretary, Michael Parker, a friend from the Navy, once revealed: “He told me the first day he offered me my job that his job, first, second and last was never to let her down.”
