‘Drawing on examples from nations with a Westminster system of government, I argue that historical practice shows that, as a matter of constitutional convention, a person can be appointed as Prime Minister when they are not a MP, as long as they will imminently become one. (I will describe this period as the ‘interim period’ but this should not be equated with holding office on a caretaker basis where conventions impose limits on the exercise of powers.)’
