Polytical is a very new UK poly organisation. They write:
We... hope to be able to contact officials and decision makers within the NHS and Education system with the aim of discussing multiple-relationships as a safe and perfectly functional choice.
A key feature we hope to get eventually is a Legal Pack that helps those in multiple committed relationships enjoy the benefits that monogamous couples get. As well as this, we will also be working to help find ways to campaign against and legally circumvent any poly-discriminatory laws such Multiple Occupancy Households licensing.
I don't know anything more about the organisation than what it has up on its site, and can't vouch for it in any way. But it looks like a positive move for the UK poly community, and, of course, the more people get involved and support it, the more successful it is likely to be. Also, the more we do to help, the less likely it is that the organisers will suffer from activist burn-out before these aims are achieved.
