The Danish postal service has announced it will cease deliveries from 30 December after 400 years. Eventually, other countries may go down a similar route

Predictions of the demise of letter writing are not new. The invention of the telegraph and the rise of the postcard were both seen as potential threats to a more leisurely, reflective form of communication. Yet by the close of the 20th century, more letters were being sent than ever, as social correspondence began to be supplemented by a boom in business mail.

From Europe’s most tech-savvy society, however, comes ominous news. As of next week, Denmark’s state-run postal service will end all letter deliveries after doing the rounds for 400 years. Around 1,500 jobs are being cut, and the country’s beloved red letterboxes are being sold off. It will still be possible for Danes to send a card or a love letter to someone far away next Christmas, but only via the shops of a smaller private company or a costly home collection.

All the incentives in Westminster politics militate against confronting difficult issues, but a failing government may as well try honesty

The formula for stable government, according to Britain’s constitution, is a big parliamentary majority and divided opposition. Sir Keir Starmer’s predicament proves that those conditions are not sufficient.

The prime minister’s inability to convince voters that he has an agenda for national renewal, and the demoralising effect that has had on the Labour party, make a leadership challenge look plausible after local elections next May. Maybe sooner.
