During the purge of dissident members of the Communist Party of Great Britain after the internal struggle over the Morning Star in 1984-5, a large part of the membership of the London District came under scrutiny. To avoid the already enormous numbers who had been expelled for failing to toe the EC line, an administrative form of vetting was adopted. Members had to reapply for membership to receive a new card.
In a detailed survey, Helen was listed as a member in Hackney South who was proposed for being re-registered in January 1986, suggesting a neutral or supportive position towards the then leadership. Others gave unsatisfactory answers to questions posed to them and further discussions were slated.
Helen died of cancer aged 47 in November 1996.
