Antivax conspiracists have been in the Reform orbit for a while. As have the climate change denial folks (which is more or less Reform policy), most recently the “15 minute city” flavour.
I have a feeling the next branch might be the “cashless society” stuff that’s brewing.
Reform seems to be the natural party for cranks, more so than UKIP was.
Except in England, where it is still largely grey and miserable. We are still patiently waiting for summer.
