It's far more complicated than left wing media. The DM also railed against BJ. The cultural elite who hate and fear populism and feared the power of people who voted for Brexit and Boris were his undoing. It is not vociferous its insidious. The BBC, the tone most newspapers, the messaging from the intellectual and seat's of academia hated BJ and they got their own way. Over what? A slice of birthday cake and a pathetic bum pincher! Boris was no worse than Thatcher, Blair, Cameron, Peel, Lord Liverpool etc none whom had more 'integrity' than Johnson who was stitched up.
