In the latter half of the 20th century, the CWO had more than a quarter of a million members and became the largest women's political organisation in the Western world.

For several decades, the women's organisation's annual conference was regularly held in the Royal Albert Hall in London.

It does this primarily through its CWO Forums – panel based discussion meetings that are generally held in the Palace of Westminster and which are open to men and women, and to people from all political persuasions.

In July 2013, the CWO announced a new workshop as an introduction for women to apply for Public Appointments and Non-Executive Director roles.
