Despite living with Ivanova, Dzhambazov was arrested while naked in bed with beautician Gaberova at her home in Euston, north London, jurors have heard.
Jurors have previously heard that Dzhambazov, 43, was in a relationship with both Ivanova and Gaberova, with the latter formerly involved with Ivanchev.
Earlier on Friday, Ivanova, a Bulgarian national, told jurors she met Dzhambazov while working in a summer job when she was 17.
“When I asked about his health, I was being told I was pressuring him,” Ivanova told jurors.
A woman accused of spying for Russia told a court her partner lied about having a brain tumour in order to lead a “double life”.
