Berlusconi. Putin. Erdogan. Farage. Le Pen. Wilders. What do all these names have in common? All have built a cult of personality on a platform of authoritarian nationalist populism. But another factor is that each one of them has built a movement which will suffer a serious, possibly even fatal blow, if one of the above were to die suddenly.
It’s a curious feature of the hard right, the centralising of power around a key figure. As Franco, Mussolini and others proved, pull the keystone figure away and the whole structure could collapse in a way that democratic centrist parties just don’t.
If Farage, Berlusconi or Putin in particular suddenly passed away in the night there’d be a actual chaos in their organisations, a genuine vacuum and lack of clear succession that could destroy the whole enterprise in a vicious struggle for power.
