Boris Johnson is obviously an alcoholic, and it is common knowledge that he is under the doctor for it. The same has been true of many successful politicians, as it still is.

Someone who wanted to return to the thoroughly illogical combination of fiscal and military hawkishness would have to be defeated by Rishi Sunak.
And the fiscally and militarily hawkish Keir Starmer will also have to be defeated. There is only one man to do that. As should have happened this year, there needs to be a head to head between Starmer and Jeremy Corbyn.
