True in the cases of France and Germany. But in the UK, Theresa was imposed upon them by the Party Powers-That-Be, as I recall. Let’s hope that this current debacle of Brexiteers having to endure Theresa May (a Remainer) as such a weak leader, especially since she is the PM expected direct something as important as Brexit, will cause Conservatives to insist upon choosing their own party’s leader this time.
The Conservative Party voted for May as leader.
