The Labour leader frequently describes himself as being from a "working class background" and often references the "pebble-dash semi" in Oxted, Surrey, where he grew up.
His dad was a toolmaker and his mum worked as a nurse. His mother suffered from Still's disease, a rare autoimmune condition which eventually left her unable to speak or walk.
He went to Reigate Grammar School, which became a private school two years after he joined. His fees were paid by the local council until he was 16.
After school, he became the first in his family to go to university, studying law at Leeds and later Oxford.
