The past weekend was a bittersweet one for the Queen who marked an incredible 70 years on the throne.
Not only did it signal the start of her Platinum Jubilee year, it also marked the 70th anniversary of the death of her beloved father, George VI.
And today, in what will no doubt be an emotional week for Her Majesty, she will mark another sad anniversary - 20 years since the death of her younger sister Princess Margaret.
