This week The Spectator ran a front page article on the current parallels between Britain and Weimar Germany. (https://www.spectator.co.uk/.../weimar-britain-lessons.../)
In this video Andrew Marr draws parallels between Reform UK's new immigration policy and the same period of history.

The interesting thing is that we are moving away from cranks on the internet invoking Godwin's Law to serious journalists and commentators warning about clear historic comparisons and the importance of not repeating them.
In his Spectator piece Michael Gove clearly points out that Reform UK are not the same as their 1930s equivalent. But it doesn't mean some future iteration won't be, it is a dangerous road that we are on.
