I have, against quite a lot of opposition here, not from everyone, I must say, said much the same thing about Jeremy Corbyn for wee while. He has handled the Brexit conundrum with some skill and great humanity (and humility). He knows the country is seriously divided about this matter, a division which cuts across the traditional party and political divide, and has tried to steer some sort of middle, compromise course, in which will please neither extreme, but which might at least keep the citizenry and the Union together, and for which he's been roundly condemned. All great divisions must heal eventually, and the sooner the better. Corbyn's realised this from the very beginning.
There's a serious psychological disturbance where people deliberately continue to open up wounds or cause chronic skin lesions as part of taking up some sort of abnormal "sick role". There are a number of specific forms of this self-mutilation, that comes under the name general description, "dermatitis artefacta". It's chronic and not easy to treat. I think you might, perhaps a bit fancifully, make this an analogy to the UK's inability to heal its own divisions in dealing with Brexit. A self-inflicted wound, continually being picked at, and never healing, indeed now festering. A political crisis artefacta? A diagnosis of a disturbed and unhappy country?
Of course, for the many cynics here, Blair's praise of Corbyn will be Blair's hammering of the last nail in Corbyn's coffin.
