Why isn’t the Tory power vacuum more exciting?

As I walked across Horse Guards one day last week, everything seemed eerily quiet. No one was about, and the only object I could see was a sleek limousine parked where one is not allowed to park, facing Downing Street. As I approached, I could read its number-plate, which said ‘1 VEN’. Was this the beginning of the long-awaited Corbyn coup, backed by fraternal aid from Nicolás Maduro? I cannot yet answer my own question for certain, because although Theresa May is still referred to as the ‘Prime Minister’ and even holds ‘cabinet meetings’, no one seriously suggests that she — or they — transact the business of government. Supporters of Boris Johnson announce what he will say at these meetings (‘£100 million extra a week for the Health Service, please’). Supporters of Philip Hammond (a select group) announce that he told Boris that he (Boris) is not allowed to say that sort of thing because he is only Foreign Secretary and Mr Hammond is Chancellor of the Exchequer.
