For Welcome Scotland (transphobic "women's rights" org) tweeted this statement from the CPGB:
Richard Shillcock of @CPBritain has sent us this statement:
We stand in support of recognising the nature of biological sex, defending sex-based rights and signle-sex services and sports, changing the Equality Act such that 'sex' means 'biological sex', and for calm, comprehensive discussion of these issues. We oppose gender self-identification and the new gender ideology. We oppose all forms of conversion therapy applied to lesbian and gay people and we oppose including trans identities in such a ban. We recognise the Cass Report as authoritative and we oppose 'gender-affirming care' and 'social transitioning' in nurseries and schools.
We oppose gender self-identification and the new gender ideology.
cool and normal! the CPGB does denounce this as "an unofficial summary of Communist Party policy" so maybe some of this is misinfo? idk correct me if there is any
then JK Rowling retweeted and replied with this:
If you were going to spoil your ballot paper, why not check this list to see whether there's a candidate in your constituency:
communistparty.org.uk/communists-party-announces-final-list-of-candidates-for-4-july-general-election/
basically vote CPGB as a protest vote of some sort
CPGB then "backed away" from this endorsement:
Concern has been expressed about a tweet issued by 'For Women Scotland' on 22 June 2024 and re-tweeted by J.K. Rowling. The tweet reproduces an unofficial summary of Communist Party policy, namely that:
"We [the CP] oppose all forms of conversion therapy applied to lesbian and gay people and we oppose including trans identities in such a ban."
The Communist Party does indeed oppose all forms of conversion therapy applied to lesbian and gay people. We also support banning regressive conversion therapy targeting trans people.
For the avoidance of doubt, the Communist Party supports the right of trans people to medically transition, to have access to healthcare and live equal, full and meaningful lives, socially, economically and politically. We believe that such liberation will only be possible under socialism.
Wherever possible, corrections to this effect have been sought where this inaccuracy has been reproduced.
...which is actually mostly inline with that they said earlier and doesn't address the whole opposing gender self-identification, "the new gender ideology" or "social transitioning" of children. another 
moment ig
All British Communist parties are 35 GCHQ agents in an overcoat at this point, if it's not this shit it's them banging on about how China is Imperialist (or sometimes it's both)
