Queen Elizabeth, the world's longest-reigning living monarch, celebrated her Sapphire Jubilee as Britain commemorated 65 years since she ascended the throne.
The 90-year-old monarch, who became Britain's longest-reigning sovereign in 2015, did not publicly mark the occasion herself, but a 41-gun royal salute was fired in a central London park to honour the landmark.
"Today's Sapphire Jubilee marks yet another remarkable milestone for our remarkable queen," Prime Minister Theresa May said yesterday.
