Brexit caused an odd selection effect in the Tory party where sensible responsible politicians such as Ken Clarke and maybe Theresa May were pushed out for pointing out the problems with Brexit and replaced but more the irresponsible fibbing variety who were prepared to deny reality and say everything with hard brexit will be great such as Boris and his fellows. Not sure where this all goes next. Maybe to Starmer who at least is responsible but will have quite the mess to deal with.
