About Donna Jackson

Donna Jackson is a fictional character from BBC medical dramas Holby City and Casualty, played by actress Jaye Jacobs. Donna entered Holby City in its sixth series as a staff nurse, characterised as a wild-child with a chaotic personal life. During her tenure, she grew to take her work more seriously, becoming a ward sister and accepting more personal responsibilities by adopting her half-niece Mia. A tart with a heart character, Donna had many romantic liaisons with her colleagues, including a one-night stand with midwife Mickie Hendrie. She ultimately fell in love with agency nurse Kieran Callaghan, and departed to be with him after he was injured in Afghanistan as part of the Territorial Army.
