A projection of how the election results would look if we used Additional Member System (AMS), like in Scotland and Wales.

| Party | AMS | FPTP | Seat change | 
|---|---|---|---|
| Labour | 236 | 411 | +175 | 
| LibDems | 77 | 71 | -6 | 
| Green | 42 | 4 | -38 | 
| SNP | 18 | 9 | -9 | 
| Plaid Cymru | 4 | 4 | 0 | 
| Reform | 94 | 5 | -89 | 
| Conservative | 157 | 121 | -36 | 
| Northern Ireland | 18 | 18 | 0 | 
| Other | 4 | 6 | +2 | 


New Zealand switched from FPTP to MMP despite the encumbant parties being like that.
It took years of organising and effort. History here https://en.m.wikipedia.org/wiki/Electoral_Reform_Coalition
The vibe in UK reminds me of NZ in the late 80s. It can be done when people really want it.
I think you give us to much credit 😉. This is the UK. We have an unlimited talent for fucking things up.
