I'm not convinced he ever will be. If, and I still think it's a big if, even if Reform win the next election I don't think he has the balls for the job. He just likes to stand on the sidelines stirring up things and spouting anything populist. Just can't see him at PMQT taking flak and being responsible for any of their policies (if they have any other than immigration.) He'll probably say he's too busy with his businesses etc. and walk away.
