The UK's Supreme Court has ruled that the legal definition of a woman is based on biological sex.
It marks the culmination of a long-running legal battle which could have major implications for how sex-based rights apply across Scotland, England and Wales.
The court sided with campaign group For Women Scotland, which brought a case against the Scottish government arguing that sex-based protections should only apply to people that are born female.
Judge Lord Hodge said the ruling should not be seen as a triumph of one side over the other, and stressed that the law still gives protection against discrimination to transgender people.
