The King’s life – from newborn baby prince in his mother’s arms to a crowned monarch sitting on his throne – has been celebrated with a collection of photos from every one of his 75 years.

Charles, who reaches his milestone three-quarter century birthday on Tuesday, is pictured being held in the air as an eight-month old by his proud father the Duke of Edinburgh in 1949.

Childhood portraits show the young future King striding along in a kilt just before his seventh birthday in 1955, and spending time with his family at Windsor Castle in 1959.
