Sherelle Jacobs in today's Daily Telegraph

"Not only does the ruling class not have the solutions, it is also oblivious to the problems. This country has been pretty much stagnant for 15 years (in Scotland, business investment has been flat since 1998). And yet the Westminster bubble is convinced that the problem is not one of systemic decay but popular psychosis, embodied by Brexit and collapsing faith in institutions and a new mania for fake news."

A very good point.

Nevertheless, she points ouț, the populists, by which she means the Brexiteers and SNP, have failed badly in the UK.

Yes and no. Brexit did happen. The SNP have ruled Scotland since 2007 and the Conservative Party has been in power since 2010 and are not populists, unfortunately perhaps. 

Both parties are in trouble now though.
