She's Queen of the castle... and he's her cheeky rascal! Adorable Prince George is given a step up as he beams proudly next to his 'Gan-Gan' in magical family portrait to mark her 90th birthday

If monarchy stands for anything, it is continuity and stability. And this superb image, captured in the White Drawing Room of Buckingham Palace reinforces that. Ahead of the Queen's 90th birthday tomorrow, the Royal Mail has released the historic image which will go on to make four unique postage stamps to mark the celebration. Perched proudly on a pile of foam blocks, but holding daddy's hand just in case, Prince George poses alongside his father, his grandfather - and the great-grandmother whose face has appeared on more stamps than anyone in history. He has been raised up a foot to ensure all the principals were at roughly the same height and spaced evenly apart so as to fit neatly inside its own perforated outline on each sheet of four stamps, which will sell for £2.56 - the regular price of four First Class stamps.
