Haha if he’s anything like Margaret Thatcher he’ll be an abject failure that makes life miserable for most of the country, other than the ultra wealthy, and people living in the capital city.
Outside of Londoners and the wealthy nobody benefitted from Thatcher, and the UK never recovered from her leadership and likely never will.
That would be a catastrophe for Argentina. Her decision to shit on producing industries and favour the financial business enterprises harmed the UK in some instances and only let to the big wealth gap between the English south and north in the end.
