A better standard of resignation.
Back in the 1950s, when policemen called you Sir and Wimbledon was contested by adults, the Crichel Down affair led to the resignation of Sir Thomas Dugdale.
He was not personally responsible for the problems with the case, and it is now widely cited as the classic example of the doctrine of Ministerial responsibility.
Nowadays, Ministers responsible for egregious failures cling on, bleating about needing the opportunity to fix their own mistakes. Opposition spokespeople fiddle taxes while preparing for high office. The Prime Minister's own fingerprints are all over various government disasters, from deregulation of the markets to the privatisation of the Tube, yet he will not go until the electorate drag him out of the door to Number Ten.
How much more impressive, therefore, is this news from Portugal. The Economy Minister made the sign of the bull to an opponent, implying someone else had got become very good friends indeed with his wife, and duly quit.
