I don't see it like that. If you lose all your experienced civil servants, you end up losing your ability to do the very things you want to do.Basically, the old firm civil service along with their associates and partners in crime are being cleaned out. Some realise that their positions are untenable under the new regime. It's no big deal and nothing to get excited about.
And it might not only be civil servants you lose:
Senior Conservative MPs and a raft of legal experts have urged the government not to go ahead with plans to drive through a change to the Brexit agreement on Northern Ireland after a minister conceded it would break international law.
The remarkable admission by Brandon Lewis, secretary of state for Northern Ireland, followed the resignation of the most senior legal civil servant and has raised questions over the future of justice secretary, Robert Buckland, and attorney general, Suella Braverman, both of whom have taken oaths to uphold the rule of law.
