In France several scholars are very active in developing the ethics of care into a full fledged political ethics. Fabienne Brugère, Patricia Paperman and Sandra Laugier are amongst them.
Have a look at this lecture by Sandra Laugier, in which she develops her idea of care as an activity, as an attitude as well as an political category.
There is easy subdivison in the different themes she reflects on, like justice and care or the question whether caritas is the historical predecessor of care, using the division in chapters.
