Mosley suggested he’d slept with Tommy’s wife Lizzie Shelby (Natasha O’Keeffe) during her days as a call girl and a nightclub hostess in Birmingham.
He went on to offer an indecent proposal, requesting to sleep with Lizzie when he came around to Tommy’s house.
However, Tommy was unimpressed and threatened to expose Mosley’s infidelity to his wife Lady Cynthia Curzon.
Tommy’s counter blackmail forced Oswald to reconsider his own request.

According to multiple sources, the fascist MP had numerous affairs with other women despite being married including Diana Mitford, who went on to become his second wife after his first died.
In previously unpublished letters that were donated to the National Library of Scotland, Mitford seemed to confirm Mosley has indeed cheated repeatedly on Lady Curzon.
After marrying Lady Cynthia in 1920, he was apparently unfaithful with his wife’s sisters Irene and Alexandra as well her stepmother Grace.
