In July 1923, on the subject of birth control, Broad ".. asked the Minister of Health whether his Department will raise any objection to birth control information being given at infant welfare centres to married women who desire it by voluntary workers attached to the centres, or otherwise to their being informed, on request, where such information can be obtained?". Mr Chamberlain replied that his ".. view is that such information as is referred to should not be given at infant welfare centres, but that women for whom it appears to be needed on medical grounds should be referred to a private doctor or a hospital".
In May 1924, Broad led a delegation of the birth control movement to the then health minister, Clydesdale Member of Parliament John Wheatley.
The delegates included H G Wells, the Honorary Mrs Bertrand (Dora) Russell, Doctor Frances Huxley, and others
