I dont think this is because of last Friday.
This is because, although slowly, some organisations are taking legal advice based on the Supreme Court ruling.
Not just businesses but also other groups such as WI.
Last friday didn't change anything, other than of course showing that GLP will apparently go on and on and on raising money to start court cases to try and reverse the Supreme Court ruling.
More worrying IMO is that Polanski is now saying it would be so easy for the Government to change the EA, why aren't they doing that to protect trans rights. ie advising anyone who will listen to him, that the UK should have an EA that has within in it enshrined that trans rights take precedence over women's rights.
