There’s plenty of groupings that oppose nuclear power, for a variety of reasons. I’m merely arguing that this grouping has been consistent in its enthusiasm for nuclear for decades.

Yes, but specifically the Labour Right are the grouping that are in power right now so their opinion matters. No-one thinks Corbyn is pro-nuclear but the stance of the Blair->Brown->Starmer axis has been extremely consistent. Without the qualification one could argue that the support was inconsistent, but nothing is further from the case. They’ve wanted this for a very long time.
