I think this is quite a useful example of the way in which Stonewall is influencing. It's a demonstration of how openly Stonewall is attempting to influence policy through third parties and an indication of how deeply it's embedded in business culture.
I've sent it to my GC MP who's immediately understood what it represents.
Like others, I'm quite heartened to see that final sentence. Seems to me that someone in NatWest has moderated the response and is trying to dial back the wokeness.
I'm going to Tweet NatWest about it from a semi-positive 'Glad to see that NatWest supports the EA2010. It's such a shame that you can't openly and actively support the right of spouses whose partners transition to leave their marriages if they wish to do so.'
