"We are not attractive to the ethically challenged"

British Virgin Islands executive director protests against tax haven image.

"We are not attractive to the ethically challenged," protests Elise Donovan, executive director of the British Virgin Islands’ financial centre. Donovan is saying that everything you think you know about the BVI – banking secrecy, half a million companies for under 25,000 residents – is wrong, or at least good.

"People who have strong business acumen know about the BVI. We have to educate the people don’t know the facts. People who know business know that the BVI is a reputable, above-board jurisdiction… There’s a misconception that we are in some sort of illicit activity, when we are part of the wheels of commerce in the global financial world."

Speaking at BVI House in Mayfair, alongside Dr Orlando Smith OBE, premier of the British Virgin Islands, and financial secretary Neil Smith, Donovan seems to chafe at the BVI’s reputation, not enhanced recently by the revelation in The Guardian of high-profile figures who had offshore accounts there.

Mongolia’s former finance minister and François Hollande’s 2012 election campaign co-treasurer were both fingered (not for illegal activity), as were Scot Young (went to jail rather than reveal assets) and Baroness Carmen Thyssen-Bornemisza (owns her art there).

Perhaps Donovan has a point. As I wrote in April, when the story broke, no-one made the point that there is nothing nefarious about legitimate offshore banking. I also argued that the investigation constitutes invasion of financial confidentiality on an enormous scale – also a point overlooked by many in their fervent tax-haven bashing. (Tax justice campaigner Richard Murphy was one who celebrated the leak.)

How was this information obtained, I ask Premier Smith (pictured left). Given that the BVI pride themselves on their banking confidentiality, the report must have been extremely embarrassing for the island’s IFC as well as off-putting for potential customers.

"[The information] was acquired illegally," Smith says firmly, "but we’re not exactly sure how. We were shocked, but we were comforted by the fact that it did not originate from our regulatory system, from the IFC or from any structures in the BVI."

Just how the data was obtained remains to be discovered, but I wonder if the premier is worried that the BVI will have sustained a reputational hit as a result of its release. He says that customers – both current and potential - needn’t be worried about the IFC’s commitment to confidentiality, despite the report.

People aren’t going to see it like that though. The BVI is not alone here in feeling that it is misunderstood as a "tax haven", in which billions of illegitimately acquired offshore dollars are stored in obscure bank accounts: all IFCs, it seems – and not just those in idyllic, sun-dosed islands – are being tarred with the same brush. As Smith says, "Any jurisdiction that deals with financial services is called a tax haven. That is just a name people use but it’s not what it’s about."

There is a difference, often overlooked, between confidentiality – in which the BVI IFC maintains "very high standards" – and secrecy, which it does not tolerate, says the premier: ‘Secrecy suggests that someone wants to hide something, confidentiality suggests you simply don’t want to have your information public. You wouldn’t want your bank information public, for example.’

I certainly wouldn’t – although I suspect it would be dull enough to avoid serious scrutiny – but some point to other aspects of the BVI to justify their suspicions that a lot of people there are up to no good. They point to the 500,000 active registered companies on the BVI, for example, so I ask financial secretary Neil Smith what they’re actually used for.

His response, at a slight angle to the question, is clearly motivated by frustration with the IFC’s public image: "The biggest misconception for me is that it is not possible to find out who owns a particular company [in the BVI]. Yes, the public won’t know, but if the UK government want to know who owns a particular BVI company then they need only ask, and that information will be provided." The BVI has 24 Tax Information Exchange Agreements in place with other countries, and signed its most recent with Canada on 21 May.

Smith is also annoyed at the idea that billions of dollars are actually stored in the BVI: "We don’t keep money here. It’s true that the BVI owns a lot of assets, but they’re not in the BVI. They may be in London or Hong Kong, but they’re not actually held here."

Even if they were though – assuming they had not been criminally acquired – that would not automatically make the account holders morally suspect. Of course, that’s never going to be the headline.

Neil Smith pleads for a fair go: "It’d be nice if the BVI is recognised for the quality of its IFC. Just put us on a level playing field, and treat us in an objective manner." Whether, in a world where large governments are bullying smaller governments to name names so they can cream off tax (the decimation of banking secrecy is incidental), the BVI will get fairness remains to be seen.

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.
