Well the engagement is presumably standard Labour Party engagement - for example I imagine the whole reason why there is a reduced rate for BAME members who go to that event which people are up in arms about is to make it more attractive for them to go. (As cack handed as that is). What was interesting from one of the recent Novara podcasts was that membership of "BAME Labour" as a group is quite low, compared to the total BAME membership. Which suggests that some people just can't be arsed with it or that signing up isn't that easy. ALSO that having a BAME Labour seat on the NEC (or some other body, I forget which) is far from representative.
