Ah, just checked their FB page again (it’s public) and it’s Sisters Uncut who are organising th protest, ATH are just publicising it on their page. No doubt they will be involved as well. They are calling it a counter-demo which is odd as the Woman’s Place event isn’t a demo as far as I’m aware?!
According the FB they intend to bring banners and whistles and make lots of noise. The post didn’t have very many likes. I’m actually wondering how many people are actually involved in these groups...
