I'm not sure you can compare the clearly democratically elected PM of NZ with the Marxist President of Venezuela.Really?
The U.K. has just given a supreme optimist an 80 seat majority.
The British left does like it’s foreign heroes, Saint Jacinda follows in the footsteps of the geezer from Venezuela and the maid from Burma, but like all political careers they Crash and Burn eventually.
Just as "everyone on the right" doesn't share the views of Nigel Farage or Hitler, so "everyone on the left" isn't beholden to Corbyn or Maduro.
