In 1970, Natalia Makarova became the first female ballet star to defect to the West from Russia.
The dancer claimed asylum during a UK tour, nine years after another Russian dancer, Rudolf Nureyev, had defected.
Natalia later joined the American Ballet Theatre in New York. She wouldn’t return to her home country for almost 20 years.
Jane Wilkinson has been looking through the archive to discover the reasons behind her defection.
