Indeed. That is now the case....
....due to some on-brand Johnson shenanigans of ditching the Fixed Term Parliament Act meaning that the next election can now be up to 8 months after the date which voters expected when last voting.
Actually they voted for 4.5 years as the Fixed Term Parliament Act was in force at the time of the last Election - which specified an Election on 2nd May 2024.
Lord Carrington was Foreign Secretary at the time of the Falklands War ( well, just before the war, he resigned because of it ).
No doubt there are many other examples.
