This is a photograph of Beryl Lund who, in 1948, was an actress, a communist and a ministry civil servant involved in sensitive defence contracts.
She appeared in a Unity Theatre revue mocking the Labour government's 'red purge' of communist civil servants - the revue was reviewed in The Times - and 'red Beryl' ended up a victim of the purge which she had sent up on stage.
