Princess Teresaโ€™s death comes weeks after King Felipe VI of Spain tested negative for the virus.

Born on July 28, 1933, Princess Maria Teresa studied in France and became a professor at Parisโ€™ Sorbonne as well as a professor of Sociology at Madridโ€™s Complutense University.

She was known for her outspoken views and activist work, which led to her nickname the โ€˜Red Princessโ€™.

A funeral service for the princess was held on Friday in Madrid.

Meanwhile, Prince Charles became the first British royal to be tested positive for the coronavirus, earlier this week.
