We used the titles usually given to the Government’s two customs options without any gloss or commentary: to have done so might have skewed the responses.

And what doing so has revealed is instructive – namely that, like the vast majority of voters for sure, what those options mean confuse or baffle even some who follow politics fairly closely.

Just over a quarter of respondents simply don’t know what option they prefer.  The remaining findings bring little joy to supporters of any of the main options – and very little indeed to those of what we read is Theresa May’s own preferred one.

A quarter of our panel, if we round up as usual, support that customs partnership model.  Over a third go for the customs maximum facilitation alternative.  One in ten esssentially want Britain to stay in the Customs Union.
