A thread earlier today discussed the WI admitting men to their membership.
I was a long-term member of the National Women's Register, a similar organisation, but my membership had lapsed over lockdown.
This morning I mailed them to ask if they allow men to join and have received this reply:
"We do not accept membership from men wishing to join NWR, however, if a man is reassigning their sex and is living as a woman and wishes to join then they can.
Please find attached a copy of our Equal Opportunities and Diversity policy which covers some guidance on this on page 3 & 4.
Please also find some information from the Equality Act, 2010."
