Theresa May, having ridden high in the nine months following her coronation as Tory leader and prime minister back in 2016, has now met with a dastardly fall. Since the June general election result - which robbed her of her parliamentary majority - everything seems to have gone belly up.

The Brexit negotiations appear to have ground to a halt. “There was nothing, zero, no progress,” said one official last week. Not surprisingly, there is now a deep sense of frustration, not to mention deep anxiety, about where things are heading. Philip Hammond, the current chancellor, has even warned that a “no deal” scenario would ground all aircraft on day one, clog up all the ports and impose a “hard” border in the North of Ireland.
