Although attention has focused on the deselections, another ongoing process is the relatively large number of other Conservative MPs who have chosen to step down at the next election.
Below is a list of all those who have announced so far, many of an age when they might still expect long service in Parliament, or even another spell in government, in earlier times.
To what extent this is a product of present circumstances, rather than simply a trend away from treating the Commons as a vocation for life, is hard to say. But every departure opens up a new selection, often in safer seats, for the current leadership to fill, and gives Boris Johnson greater scope to shape the parliamentary Conservative Party.
P.S: John Bercow is also standing down.
