When BT earmarked the kiosk for closure in January, Derek Harris began to campaign. The fight gave him purpose at a difficult time in his life

• ‘I don’t want it to die’: one man’s battle to save the last phone box in his village

The caller display flashes up: “Derek in the K6” it reads. On the line is Derek Harris, ringing from the red phone box he saved for his village. When he saw, on the agenda for the parish council meeting, that BT had earmarked it for closure, Harris knew he had to fight it. “It’s fighting for what is valuable, cherished,” he told me when I went to meet him in February, sitting over coffee in a cafe near Sharrington, the Norfolk village that has been his home for more than 50 years, and the phone box for longer. It’s a K6, for Kiosk No 6, designed in 1935 by Sir Giles Gilbert Scott.

For a few weeks, Harris, then 89, became a media star. One of the criteria for keeping a phone box in use is that at least 52 calls have to be made from it in a year (fewer than 10 had been made in 2024). As the campaign picked up speed, one day a queue of people made more than 230 calls from the K6. Harris sparked a national conversation about the continuing need for kiosks in an age of mobiles. Behind the scenes, he was a tenacious activist, sending constant emails to his MP, councillors, and of course, BT. Some of them included photographs he had taken of BT vans whose engineers were working nearby, as proof the phone box could be easily maintained. In March, BT decided to reverse its decision.

As the billionaire retires, he leaves memorable advice from his annual letters that include pithy takes on bubbles, discipline and long-term goals

Warren Buffett, the billionaire investor who is retiring at the end of 2025, has entertained and educated shareholders in his Berkshire Hathaway conglomerate for many years with his pithy annual letters outlining the firm’s performance.

Every year since 1965 he has updated his investors on the journey as Berkshire morphed from a “struggling northern textile business” with $25m of shareholder equity when he took over, to an empire worth more than $1tn.

Though the price I paid for Berkshire looked cheap, its business – a large northern textile operation – was headed for extinction.

My error caused Berkshire shareholders to give far more than they received (a practice that – despite the biblical endorsement – is far from blessed when you are buying businesses).

Woody Allen once explained why eclecticism works: ‘The real advantage of being bisexual is that it doubles your chances for a date on Saturday night.’

When such a CEO is encouraged by his advisers to make deals, he responds much as would a teenage boy who is encouraged by his father to have a normal sex life. It’s not a push he needs.

Andrew destroyed a few small insurers. Beyond that, it awakened some larger companies to the fact that their reinsurance protection against catastrophes was far from adequate. (It’s only when the tide goes out that you learn who’s been swimming naked.)

In our view, however, derivatives are financial weapons of mass destruction, carrying dangers that, while now latent, are potentially lethal.

Participants seeking to dodge troubles face the same problem as someone seeking to avoid venereal disease: it’s not just whom you sleep with, but also whom they are sleeping with.

From this irritating reality comes the first law of corporate survival for ambitious CEOs who pile on leverage and run large and unfathomable derivatives books: modest incompetence simply won’t do; it’s mind-boggling screw-ups that are required.

When downpours of that sort occur, it’s imperative that we rush outdoors carrying washtubs, not teaspoons. And that we will do.

Naturally, I was delighted to attend Mrs B’s birthday party. After all, she’s promised to attend my 100th.

She sold me our interest when she was 89 and worked until she was 103. (After retiring, she died the next year, a sequence I point out to any other Berkshire manager who even thinks of retiring.)

The candidates are young to middle-aged, well-to-do to rich, and all wish to work for Berkshire for reasons that go beyond compensation.

(I’ve reluctantly discarded the notion of my continuing to manage the portfolio after my death – abandoning my hope to give new meaning to the term ‘thinking outside the box’.)

The Guardian’s sex advice columnist has answered countless questions over the last two decades. As the column ends, here’s what has struck and surprised her

People find it so hard to talk about sex, so if someone takes the time to sit down and write a question, then send it to the Guardian for me to answer, I always regard that as a great privilege. In the 20 years of writing the column, I have been reminded how many people are still out there, living their lives in quiet desperation about something that’s really troubling them sexually. Often the solution is more education; they just need to learn something, or be helped to be more open about a problem.

So many people grow up without the message that sex is healthy and important for a person’s quality of life, and they feel guilty every time they have sex, or think a sexual thought. They haven’t been able to enjoy sexuality and discover who they really are. Sometimes, it’s not the sexuality that is causing someone’s problem, it’s societal notions – prioritising monogamy, for instance – that makes life difficult. One of the things I would have liked to have addressed more was sexuality when people have serious disabilities or illness. Many people think they can’t continue to be sexual beings, and often that idea is pushed by people around them – that, to me, is tragic.

Either say you can’t make it well in advance or keep stumm

As New Year’s Eve looms, I implore you to heed this party etiquette advice. There are only two correct times to decline a party invitation: well in advance or not at all. The last thing any stressed-out host wants to receive, in the moments before their big event begins, is a sudden flood of 11th-hour RSVPs from guests announcing that they’re not coming. And yet, as anyone who regularly organises large parties in Britain knows, that’s exactly what they tend to be sent. It needs to stop.

Having an invitation turned down in advance stings a little, but it is genuinely helpful. It provides a sense of potential turnout to help gauge catering and expectations. A decline on the day, however, is infuriatingly useless. Food and booze will already long since have been ordered, and it’s way too late to invite another friend to make up the numbers.

In this Christmas special, four previous MasterChef winners compete for the ‘ultimate’ accolade. Grace Dent is a joy, while Torode bows out in a … very maverick way indeed

So. Farewell then, John Torode. You were the co-presenter of MasterChef and Celebrity MasterChef. Until you weren’t. But first, and finally, there is this: the second of two festive specials in which we watch the Australian peering at potatoes while pretending we don’t know the BBC chose not to renew his contract in July after an allegation against him using “an extremely offensive racist term” was upheld. (Torode denies the allegations and claims to have “no recollection” of the incident).

So, let’s scurry past the indignities (the two unaired Christmas specials from 2024; the summer of “MASTERCHEF CHAOS” headlines; the aired-but-with-two-contestants-edited-out-at-their-request series of MasterChef; Gregg Wallace) and remember him this way: staring blankly in linen as a panicking former credit controller from Hackney drops half a lobster on the studio floor.

Israeli prime minister said he will award Trump with Israel prize, highest civilian honor, while visiting Mar-a-Lago

Donald Trump has warned that Hamas will have “hell to pay” if it fails to disarm while offering full-throated support to Benjamin Netanyahu during a meeting with the Israeli prime minister in Florida.

In a bravura display of mutual admiration, Netanyahu announced that the US president would be awarded the Israel prize, the country’s highest civilian honour, which since its inception in the 1950s has never before been given to a non-Israeli person.

Minutes of travel expenses of former Duke of York as UK trade envoy withheld from National Archives

• Blair pressured officials over case of UK soldiers accused of beating Iraqi man to death, files show

• ‘Too complacent’: how Blair’s advisers misjudged his disastrous WI speech

• Brown’s allies could wreck Labour’s 2005 election hopes, Mandelson warned

The Cabinet Office has been accused of covering up for the royal family after the release of documents including some relating to travel expenses for the former Duke of York as UK trade envoy were withheld at the last minute.

Files released to the National Archives include documents relating to the death of Diana, Princess of Wales, and a grovelling apology from John Major’s office after an official birthday telegram to the Queen Mother was addressed in an “improper manner”.

Exclusive: Scientists uncovered biological strands using artificial intelligence and hope discovery will revolutionise treatment

Scientists have discovered two new subtypes of multiple sclerosis with the aid of artificial intelligence, paving the way for personalised treatments and better outcomes for patients.

Millions of people have the disease globally – but treatments are mostly selected on the basis of symptoms, and may not be effective because they don’t target the underlying biology of the patient.

Russia’s claim it foiled drone attack on Putin residence shows ‘they do not want to finish this war’, Ukrainian president says

Volodymyr Zelenskyy has accused Russia of trying to sabotage peace talks and preparing to bomb government buildings after the Kremlin said it had foiled a Ukrainian drone attack on Vladimir Putin’s residence.

Zelenskyy described the claim as “typical Russian lies” following his two-hour meeting on Sunday with Donald Trump in Florida. He said Russia was “at it again” and using “dangerous statements” to undermine “diplomatic efforts” with the US to end the conflict.
