It's a ridiculous chart. There isn't really 'far-right' economics. 'far-right' parties are usually as pro state-intervent as left-wing parties.
Far-right economics, if such a thing exists (we would normally call it liberal) would be all about flat rates of tax at very low levels, zero-market intervention and things like that. That most definitely is not what is happening, even if it could be considered a small step in that direction, which is debatable..like I said, borrowing to give everyone Ł400 to mitigate the costs of the energy market isn't a move in that direction at all.
It's a bizarre and inaccurate chart
