The Queen is celebrating her Sapphire Jubilee, or 65 years on the throne.

Queen Elizabeth has become the first British monarch to reach their Sapphire Jubilee, with royal gun salutes to mark the historic day.

Royal gun salutes were staged in London on Accession Day, as is the tradition, with a 41-gun salute by the King's Troop Royal Horse Artillery in Green Park at noon.

Royal Mail issues a Sapphire Blue £5 stamp.

A portrait by David Bailey, taken in 2014 and showing the Queen wearing a suite of sapphire jewellery given to her by King George VI as a wedding gift, has also been reissued.
