'She's the Queen to us.... but to George she's Gan-Gan': Just one of the gems revealed in special tribute featuring more members of the Royal Family than any television show before it

A candid new documentary featuring more royals than ever before reveals some never before seen insights into the Queen's life as she reaches her 90th birthday. 

The Duchess of Cambridge reveals that her son Prince George calls the Queen Gan-Gan. 

For much of the last year, during which the Queen has become the longest-reigning monarch in British history, a documentary team has been granted privileged access to the Queen and to those who know her best. 

The result is Our Queen At Ninety, a historic two-hour ITV documentary which will be broadcast for the first time on Easter Sunday. Like the record-breaking monarch it celebrates, it's a programme with a record of its own since it includes contributions from more members of the Royal Family than any royal documentary ever made.
