Does "chemicals" include drugs for lethal injection executions in the US?
Much as I am sure the Torys would love for the UK to lead the world in execution consultancy (I can see a "Bake Off"/"Condemned last meal" tie up in the making. "Hairy Bikers on Death Row" ?, "Strictly Lethal !" ?") the EU has an EU-wide ban on the export of lethal injection chemicals.
Of course, with the UK on course to leave the EU, we can "take back control" and flog oil drums of the stuff. Enough execute all the prisoners on death row - even the white ones.
Brexit - the gift that keeps on giving ....
Michael Portillo fronted a documentary a while back "How to kill a human". The image of a US prison governor saying that the death penalty "had to hurt, or there was no point" was one of the most telling testaments to the barbarity of it I have ever seen.
