What about MSBS
Abbott's pronouncement included Vet's Affairs recipients, DFRB, DFRDB, MSBS and another sector of pensioner which I cannot recall right now - but had something to do with defence related disability allowances.
All these areas have been notorious for having been "left behind" when the constituent make-up of the CPI was redetermined about 25 years ago (and then again about 8 years ago). The fall-behind factor has now ballooned very considerably. Just look at the graph earlier on this thread (and the Military Forum thread) - and extrapolate the divergences to the right (to the present and into the future).
Notably the UK govt has recently promised to adjust military pensions in accordance with the RPI - despite their economy being in total tatters.
