JK Rowling has called for Keir Starmer to apologise following the Supreme Court’s ruling on the term, woman. Last Wednesday, the Supreme Court ruled that the term “woman” is based on biological sex. This means transgender women who have a gender recognition certificate are not “women” under law.

The “Harry Potter” author “toasted” with champagne before announcing, “Think I might be having a cigar later.”

Rowling also posted a copy of a newspaper reporting the Supreme Court’s decision, writing, “Don’t f*** with Scottish women.”
