It has been alleged that she was an early member of Archibald Ramsay's Right Club from its founding in May 1939, but this seems unlikely as she was one of those protesting publicly against German persecution of the Jews in November 1938.

[citation needed] In 1932, as MP for Willesden West, she spoke out against a clause in the National Health Insurance and Contributory Pension Bill which would penalise all married women as 'malingerers and cheats until they have definitely proved that they are not', though they had paid fully into the fund.

She spoke of the effects of illegitimacy upon children whose parents were unable to marry because 'they are legally tied to partners who are in prison or in an asylum'.

978[25] At an inquest on her death in 1947 the Coroner for Westminster found that she had committed suicide while her mind was disturbed through ill-health.
