The real reason Julian Assange sought asylum

The WikiLeaks chief fears he could face the death penalty in the US for treason.

WikiLeaks is well-known for dropping surprises. But when the whistleblower organisation posted a tweet yesterday afternoon saying “stand by for an extraordinary announcement,” it is doubtful even one of its 1.5 million followers could have predicted what was coming.

Four hours and forty minutes later WikiLeaks dramatically announced that its editor-and-chief, Julian Assange, was at the Ecuadorian embassy in central London where he had made a request for political asylum. Ecuador’s foreign affairs ministry issued a confirmation, saying it was evaluating Assange’s request. Meanwhile it looked like the country’s foreign minister, Ricardo Patiño Aroca, had already made up his mind as he took to Twitter, posting a series appearing to back the 40-year-old Australian. “We are ready to defend principles, not narrow interests,” he wrote.

Why did Assange take such a drastic course of action? Last week Supreme Court judges ruled he would have to be extradited to Sweden to be questioned over sexual misconduct accusations made against him there in 2010. He has been fighting the extradition for more than eighteen months, principally because he believes that if he is sent to Sweden, he could be held incommunicado and then be ultimately handed over to authorities in the United States, where a Grand Jury is actively investigating him over WikiLeaks’ publication of classified US government documents.

In a statement, Assange said that he was in a “state of helplessness” and felt abandoned by the Australian government, who had failed to intervene in his case. He added that he had been attacked openly by top politicians in Sweden and feared he could eventually face the death penalty in the US for the crimes of treason and espionage.

The timing was unexpected, because the WikiLeaks founder still had the option of asking the European Court of Human Rights to hear an appeal. But in some ways seeking refuge at the Ecuadorian embassy was an obvious choice. Assange interviewed the country’s president, Rafael Correa, recently for his television show, and the two men had a rapport (“WikiLeaks has strengthened us,” Correa beamed). Ecuador previously offered Assange a safe haven in 2010, just a few months before it expelled the US ambassador following WikiLeaks revelations. (It is worth noting, however, the country is not exactly aligned with WikiLeaks ideologically: it has a record on free speech that Human Rights Watch says is the poorest in the region after Cuba.)

Assange will not have taken the decision to ask for asylum lightly. It is a huge step borne out of clear desperation, with massive ramifications to boot. For eighteen months he has been obediently adhering to strict bail conditions – subjected to a curfew forcing him to stay a registered address between the hours of 10pm and 7am, an electronic tag strapped around his ankle that can track his movements. Now Assange is in breach of those conditions and, as a result, the thousands of pounds supporters pledged to secure his release from jail in 2010 may be forfeited.

Police will be actively seeking his arrest – though are currently powerless to do so, as under the terms of the Vienna Convention on Diplomatic Relations an embassy is considered “inviolable.” That means UK authorities are not allowed to enter “except with the consent of the head of the mission.” Assange should therefore be safe so long as he is within the confines of the embassy. If he tries to leave, however, he could find himself in trouble.

Historically, people who have sought refuge in embassies have met different fates. Dissident Chinese lawyer Chen Guangcheng recently fled to the US embassy in Beijing China and negotiated a quick and safe passage out of the country on a flight to New York. But others have not been so lucky. In 1956 a leader of the Hungarian uprising, wanted by Soviet authorities, took refuge at the US embassy in Budapest and ended up spending the next 15 years inside its compound, watched by police around the clock.

For Assange, a man haunted by fears of solitary confinement and a draconian US prosecution, 15 years inside an embassy compound may sound like a preferable option.

Inside Big Ben: why the world’s most famous clock will soon lose its bong

Every now and then, even the most famous of clocks need a bit of care.

London is soon going to lose one of its most familiar sounds when the world-famous Big Ben falls silent for repairs. The “bonging” chimes that have marked the passing of time for Londoners since 1859 will fall silent for months beginning in 2017 as part of a three-year £29m conservation project.

Of course, “Big Ben” is the nickname of the Great Bell and the bell itself is not in bad shape – even though it does have a huge crack in it.

The bell weighs nearly 14 tonnes and it cracked in 1859 when it was first bonged with a hammer that was way too heavy.

The crack was never repaired. Instead the bell was rotated one eighth of a turn and a lighter (200kg) hammer was installed. The cracked bell has a characteristic sound which we have all grown to love.

Big Ben strikes. UK Parliament.

Instead, it is the Elizabeth Tower (1859) and the clock mechanism (1854), designed by Denison and Airy, that need attention.

Any building or machine needs regular maintenance – we paint our doors and windows when they need it and we repair or replace our cars quite routinely. It is convenient to choose a day when we’re out of the house to paint the doors, or when we don’t need the car to repair the brakes. But a clock just doesn’t stop – especially not a clock as iconic as the Great Clock at the Palace of Westminster.

Repairs to the tower are long overdue. There is corrosion damage to the cast iron roof and to the belfry structure which keeps the bells in place. There is water damage to the masonry and condensation problems will be addressed, too. There are plumbing and electrical works to be done for a lift to be installed in one of the ventilation shafts, toilet facilities and the fitting of low-energy lighting.

Marvel of engineering

The clock mechanism itself is remarkable. In its 162-year history it has only had one major breakdown. In 1976 the speed regulator for the chimes broke and the mechanism sped up to destruction. The resulting damage took months to repair.

The weights that drive the clock are, like the bells and hammers, unimaginably huge. The “drive train” that keeps the pendulum swinging and that turns the hands is driven by a weight of about 100kg. Two other weights that ring the bells are each over a tonne. If any of these weights falls out of control (as in the 1976 incident), they could do a lot of damage.

The pendulum suspension spring is especially critical because it holds up the huge pendulum bob which weighs 321kg. The swinging pendulum releases the “escapement” every two seconds which then turns the hands on the clock’s four faces. If you look very closely, you will see that the minute hand doesn’t move smoothly but it sits still most of the time, only moving on each tick by 1.5cm.

The pendulum swings back and forth 21,600 times a day. That’s nearly 8m times a year, bending the pendulum spring. Like any metal, it has the potential to suffer from fatigue. The pendulum needs to be lifted out of the clock so that the spring can be closely inspected.

The clock derives its remarkable accuracy in part from the temperature compensation which is built into the construction of the pendulum. This was yet another of John Harrison’s genius ideas (you probably know him from longitude fame). He came up with the solution of using metals of differing temperature expansion coefficient so that the pendulum doesn’t change in length as the temperature changes with the seasons.

In the Westminster clock, the pendulum shaft is made of concentric tubes of steel and zinc. A similar construction is described for the clock in Trinity College Cambridge and near perfect temperature compensation can be achieved. But zinc is a ductile metal and the tube deforms with time under the heavy load of the 321kg pendulum bob. This “creeping” will cause the temperature compensation to jam up and become less effective.

So stopping the clock will also be a good opportunity to dismantle the pendulum completely and to check that the zinc tube is sliding freely. This in itself is a few days' work.

What makes it tick

But the truly clever bit of this clock is the escapement. All clocks have one - it’s what makes the clock tick, quite literally. Denison developed his new gravity escapement especially for the Westminster clock. It decouples the driving force of the falling weight from the periodic force that maintains the motion of the pendulum. To this day, the best tower clocks in England use the gravity escapement leading to remarkable accuracy – better even than that of your quartz crystal wrist watch.

In Denison’s gravity escapement, the “tick” is the impact of the “legs” of the escapement colliding with hardened steel seats. Each collision causes microscopic damage which, accumulated over millions of collisions per year, causes wear and tear affecting the accuracy of the clock. It is impossible to inspect the escapement without stopping the clock. Part of the maintenance proposed during this stoppage is a thorough overhaul of the escapement and the other workings of the clock.

The Westminster clock is a remarkable icon for London and for England. For more than 150 years it has reminded us of each hour, tirelessly. That’s what I love about clocks – they seem to carry on without a fuss. But every now and then even the most famous of clocks need a bit of care. After this period of pampering, “Big Ben” ought to be set for another 100 or so years of trouble-free running.
