Civil servants have been accused of caving in to last-minute pressure from transgender activists that will make it easier for people to pick their sex in the UK Census.
The campaign group Fair Play For Women has launched a High Court challenge against the Office for National Statistics (ONS) for letting respondents to the Census on March 21, which will cost £1 billion, choose the sex that appears on legal documents such as their passport.
They are angry that the last-minute decision allows the use of documents that can be changed with a single note from a doctor.
