The Royal Family Collection

It is also one of Britain's smallest palaces and yet events at Holyrood have determined the fate of three countries - England, France and Scotland. It was also the last place where a royal prince challenged the right of an English king to sit on the throne. Fiona Bruce discovers remarkable objects from the Royal Collection that are intimately bound to the Palace's turbulent history - from the spectacular Darnley Jewel with its many hidden messages to the cat-and-mouse needlework of a doomed queen.

Film-maker John Bridcut has been granted access to the complete collection of Her Majesty's personal ciné films, shot by The Duke of Edinburgh and The Queen herself, as well as by King George VI and The Queen Mother. Much of the footage has never been seen publicly before. Various members of the Royal Family take part, contributing their own personal insights into the woman they know both as a member of their own close family and as Queen. Among those taking part are the Prince of Wales, the Duke of Cambridge, Prince Harry, the Princess Royal, and Princess Alexandra, who has never before given an interview.

Her Majesty The Queen has met more people, visited more places and lived longer than any British Monarch. In 2015, she also became the longest-reigning British Sovereign. It is no exaggeration to say that she is the most respected head of state on the world stage today. But Her Majesty’s 90th birthday in April 2016 is a personal milestone - one which does not involve record books or historical assessments. It is a straightforward celebration: of a long life, still very much lived to the full, at the heart of national life and at the head of a devoted family.

William, Kate and George: A New Royal Family is a timely portrait of two young people, and their young son, who are destined to become King and Queen of England. With extensive access and exclusive footage, this special covers major events including: the birth of third-in-line to the throne Prince George and his presentation to the world; their first official royal tour as a family; and Kate's first solo official duties since becoming a fully-fledged royal. The special also reveals how the Queen has taken Kate under her wing to prepare her for public life; and how, despite their royal wealth and privilege, William and Kate are determined to keep their connection with ordinary people.

Buckingham Palace may be just about the most famous building in the world, but its story is much less familiar. Fiona Bruce reveals how England's most spectacular palace emerged from a swampy backwater in just 300 years. The journey of discovery takes her from the sewers of London to the magnificent State Rooms; from a home for camels and elephants to the artistic brilliance of C18th-century Venice; and from a prince's Chinese fantasy to the secret of how the Palace's glittering chandeliers are cleaned today.

From the bowels of the Castle to the heights of the battlements, Fiona encounters all manner of royal treasures - from the musket ball that killed a naval hero to table decorations in gold and silver and encrusted with jewels; from the triple-headed portrait of a king who lost his head to Queen Mary's Dolls' House with running taps, and a secret garden hidden in a drawer. All of this was almost lost in the disastrous fire of 1992.
