Talk:Representation of the People (Equal Franchise) Act 1928

Coming into force
Can anyone clarify exactly when women under 21 could first actually vote? It would be useful if the article could include this.

Jennie Lee, Baroness Lee of Asheridge's article says: "At the time of the by-election [21 March 1929] women under the age of 30 were not yet able to vote" (notable because Lee was a woman aged 29, and was elected).

My first instinct was that sounded wrong, because this act came into force in July 1928. However, the text of the act says:

This seems to imply that women were actually only able to vote from 1 May 1929, so Lee's article is correct? Can anyone think of a source that would allow this to be put explicitly in the article? TSP (talk) 15:58, 4 November 2020 (UTC)
