Parents usually name their babies after people they admire. Names like Rohan [after Kanhai], Shawn [after Sean Connery], Babita [after a Bollywood star], Imran [after cricketer Imran Khan], Allan [after cowboy actor Allan Ladd] etc.
Naturally, up to 1990 people in the PPP had admired certain Russian, Cuban and other socialist/progressive personalities. Ranji Chandisingh named his son Yuri [after the spaceman Gagarin] and Brindley Benn named his son Robeson [after the Afro-American communist Paul Robeson].
That is their right.
