He is tone deaf. Tin eared. Blind. Clueless. A political machine with no emotional software installed. A man so utterly devoid of instinct that he can stand in the middle of a national crisis, surrounded by electoral wreckage, public fury, Labour panic, economic decay, illegal migration chaos and international humiliation, and still deliver another dreary sermon about process, Europe, growth, partnership and other embalmed phrases scraped from the inside of a civil service briefing folder.
