"No matter how hard you work or how capable you are, you can't do it all yourself. You have to seek reliable help." Those were Margaret Thatcher's words in 1990. Who are the 'help'? How did they enable women to have successful careers?

Ros Taylor talks to Lucy Delap and Emma Casey about how the servant died out after the two world wars – but domestic help never went away.

Lucy Delap is Professor in Modern British and Gender History at the University of Cambridge. She is the author of Knowing Their Place: Domestic Service in Twentieth Century Britain.

Emma Casey is the author of The Return of the Housewife: Why Women are Still Cleaning Up. She is a reader in sociology at the University of York.
