Other than failing to machine gun the channel migrants or make France build a giant fence around their coast I don't see brexit as the issue pushing the release of this stuff. More likely its Owen Paterson (not saving him and making an arse of it), covid restrictions boiling the pish of the libertarian wingnuts like Swayne and Baker and the new clutch of red wall tories getting comprehensively shafted.
Whatever it is that's prompting this drip feeding of scandals and death by a thousands cu(n)ts, it's isn't the fact he's a lying, scheming, despicable arsehole that is completely unfit to hold public office, as that's not new.
