Given one of the major themes of the leave campaign was "restoring parliamentary sovereignty", it's darkly ironic that leave also campaigned against parliament actually using that sovereignty, and indeed came closer than anyone else (including the EU) to restricting parliamentary sovereignty.
I wouldn't call it ironic. The forces behind Leave were - still are - far-right nationalists and wannabe autocrats. They consider democracy an annoyance - ideally a temporary one.
Their idea of sovereignty is telling everyone else what to do. They wrap this up in flags and Sptifire biscuit tin patriotism for the poorly educated, but it's all for show.
What they want is unlimited power over others. The EU has always been an obstacle to that.
The different nationalists - the Republicans in the US, the Putinists in Russia, the Zionists in Israel, the Brexiters in the UK, the Saudi oil imperialists - are all tentacles of the same creature, and more likely to cooperate with each other against their native populations than act independently.
