They began an affair; she was cited as a co-respondent in Birdwood's divorce case and became his second wife after the divorce was finalised in 1954. Her husband was the son of Field Marshal William Birdwood, 1st Baron Birdwood); after his father died he succeeded to the title in 1951. In the 1950s, she was a prominent supporter of the emigre group, the Association of Ukrainians in Great Britain, dominated by supporters of the extreme right-wing Organization of Ukrainian Nationalists (OUN). Through her work with the Association of Ukrainians, she befriended Yaroslav Stetsko, an OUN leader who read out the declaration proclaiming a Ukrainian state in 1941. Stetsko had organised a pogrom in Lviv on 30 June 1941 that killed thousands of Jews and Poles. A central aspect of the OUN's ideology was the belief that nations had to stay racially "pure" to be successful, and hence the OUN made it clear that in the Ukrainian state it wished to establish that there would be no minorities. In 1961, she visited South Africa, where she praised "apartheid" as an "inevitable and a social necessity". Strongly opposed to independence for the colonies of the British empire, she joined the Monday Club, which represented the right-wing of the Conservative Party opposed to decolonisation.
