Have a look at who Nigel Farage is. Anyone who supports Farage can very well be a member of the Trump-club. Note that Farage now also has support from a lot of people who won't like Trump. This is because uk media and now also Labour are validating Farage's xenophobia.

Some people love the hate Trump stands for.

The Russian disinformation campaign hooks people in globally. We've got our own subset in Aotearoa New Zealand, spitting the same factless clichés with no shame or reason.

Considering the labour is actively trying to cozy up to the tories, a far right party is gaining power, and the constantly rising transphobia? Are you really surprised that there are British Trump supporters?
