Four months after Wales nationalised their rail services, Scotland has announced that it will nationalise it's railways, obviously this has been an outcome of the slump in passenger numbers due to the ongoing COVID-19 pandemic.
Given that two major rail franchises in England, LNER and Northern, are already run by the government through its operator of last resort, and also that the Office of National Statistics has said a year ago that the rail service had been effectively nationalised due to treasury support, why doesn't the UK government simply nationalise the entire rail service, in effect doing in de jure, what it is doing in de facto?
