To recover, the Scottish Yes campaign needs to go on the attack

The pro-independence camp can't afford to spend the next 20 months simply responding to aggressive unionist and media questioning.

By the time Mitt Romney formally launched his bid for the US presidency in late summer 2012, the race for the White House was already more or less over. For the preceding 12 months, the former Massachusetts governor had poured all his energy into securing the Republican nomination from his conservative rivals, leaving the Democrats free to bury his reputation as a successful entrepreneur under a volley of personal attacks. These attacks cast Romney, not entirely inaccurately, as a predatory capitalist whose business practices at Bain Capital had put thousands of ordinary Americans out of work or into bankruptcy. The result was that in the weeks leading up to 6 November, Romney spent more time fending off accusations that he was ‘out of touch’ than he did explaining his policies or scrutinising Barack Obama’s record. Romney’s mistake was to allow his public image to be defined negatively by his opponents before he had a chance to define it himself. 

A comparison can be drawn between Romney’s experience and the situation Scotland’s pro independence movement currently finds itself in. Since the launches of the official 'Yes' and 'No' campaigns last year, the unionists have been far more effective at setting the terms and conditions of debate than the nationalists have. On a series of issues, most notably the currency and (until yesterday) Scottish membership of the European Union, Better Together, the official vehicle of unionism, has forced the SNP onto the back-foot. Time and time again, Scottish government ministers have been rushed out to provide what seem like hurried or improvised responses to awkward questions. With his relentless emphasis of the apparent "risks" and "hazards" of separation, Better Together chairman Alistair Darling has become an almost ubiquitous presence on Scottish TV screens. Darling’s rhetoric reflects the No camp’s key theme: that the consequences of Scotland leaving the United Kingdom are uncertain and uncertainty is bad for the Scottish economy. 

With at least two recent polls showing a decline in support for independence, there is good reason to believe this strategy is working. The unionists have an additional advantage in the fact Scottish political culture is dominated by an essentially conservative middle-class with little enthusiasm for far-reaching constitutional reform. Worse still for the Yes campaign, the Scottish government doesn’t intend to publish its White Paper on Independence, clarifying its proposals for an independent Scottish state, until the end of the year. This grants Better Together yet more time in which to compound voters’ anxieties, increasing the likelihood that, come the final stages of the referendum debate, it will be too late for the SNP and its allies to rescue independence as a credible constitutional option in the eyes of the Scottish electorate. 

There is another reason the pro-independence movement has struggled in the referendum PR battle: a lack of structural discipline. Although the majority of Yes Scotland activists are members of the SNP, the organisation itself is made up of a broad coalition of groups, each with their own ideas about how independence should be achieved. To some extent, this laissez-faire style acts as a source of creativity, generating new initiatives, like the Radical Independence Conference, and genuine excitement at the grassroots level. (600 people attended the launch of Yes Glasgow earlier this month.) But it also makes the task of developing a coherent message about independence extremely difficult. By contrast, Better Together is a considerably smaller and less cumbersome outfit, with a much more tightly controlled and clearly defined narrative. Its role - to erode trust in Alex Salmond and reinforce widespread concerns about secession - is relatively uncomplicated. 

So how might Yes Scotland regain the initiative? A more effective Yes campaign would balance its aspirational account of Scotland’s ‘journey’ from devolution to independence with a critique of the British state, highlighting the democratic and international costs Scotland pays for remaining part of the UK. In particular, it would make clear the link between Scotland’s abysmal social record (one of the worst in western Europe) and the concentration of political and economic power in London and the south east. It would also aim to systematically undermine the Scottish public’s confidence in the desire and capacity of Westminster to act in Scotland’s interests, even if this means abandoning its much vaunted commitment to positive campaigning. The one thing it can’t afford to do is spend the next 20 months responding to aggressive unionist and media questioning. 

Of course, it was the use of exactly these sorts of ‘negative’ tactics that secured Obama’s second presidential term. Recognising that the circumstances of the 2012 election were going to be very different from those of the 2008 one, Obama and his team discarded the transformative rhetoric of "hope" and "change" for a harder, more cynical approach, turning what should have been Romney’s greatest asset - his commercial success - into his greatest weakness through a sustained media offensive. Likewise, the SNP needs to acknowledge that the 2014 referendum will not be a re-run of its 2011 electoral triumph, when it bulldozed its way to victory on the back of what one commentator called a nationalist "juggernaut of joy." The independence vote will take place against a backdrop of high unemployment, recession and austerity imposed by a discredited and corrupt Westminster class increasingly at odds with Scottish political values and preferences. There is a deep well of political dissatisfaction in Scotland: advocates of independence need to learn how to exploit it.

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.
