There is an alternative: governments can do what markets cannot

To succeed in age of globalisation, British manufacturers need a government that rejects laissez faire Thatcherism.

In the wake of Baroness Thatcher’s funeral last week, there has been much revisiting of the 1980s and her legacy. Though there are disagreements as to the benefits of her approach, there is one thing on which we can all agree: for better or worse, she did change Britain.

One impact of the revolution her policies unleashed was that too much of our manufacturing base was undermined. Nevertheless, Britain remains the ninth largest manufacturer in the world today, and a global leader in many areas of advanced manufacturing. The best of British manufacturers have shown they can meet the challenge of global competition.

For example, since Labour’s establishment of the Automotive Council – and the continued backing of it by this government – Britain has confirmed itself as a great place to make cars. The sector has attracted investment on an unprecedented scale and is on track to break the record for car production set in 1972.

What it means to be a leading manufacturer is changing as well, as the divide between the service and manufacturing sectors has become blurred. Last week I visited Rolls Royce, a global leader in aerospace. The majority of Rolls Royce’s revenues are generated not from manufacturing but from after sales service contracts. This shows how the benefits of a strong manufacturing base can spill over into other sectors, generating more of those well paying and satisfying jobs that our economy needs.

So the potential is there to grow our manufacturing base further. But British manufacturers need a government that backs their ambition. They need a proper, modern industrial strategy – demanding in its ambition and effective in its execution. This is not something which sits comfortably with laissez faire Thatcherism.

George Osborne – a disciple of the laissez faire approach - promised a "march of the makers". But overall, and despite a significant fall in the value of the pound, the reality simply has not matched his rhetoric. The latest trade figures were terrible, with the recent fall in exports reflecting a downward pattern that started in October 2011 according to the ONS. Companies with cash lack the confidence to invest. Firms needing finance to expand can’t get it.

One of the maxims of the neoliberal economic revolution Thatcherism unleashed was that governments must be subservient to markets. There was, Mrs Thatcher said, "no alternative". Recent history warns of the limits of this approach. It is also becoming abundantly clear that globalisation, far from limiting the space for governments to act, is making such action more important. It is not surprising that northern European economies which have pursued industrial strategies and applied a different model to Thatcherism have largely maintained their shares of expanding global trade through policies that work together to reinforce areas of national strength. 

Governments can do what markets cannot: they can help firms work together to address shared problems over skills or R&D, even as these businesses compete fiercely for custom. Governments can give direction and support to the animal spirits that drive investment and innovation. Through strategic use of procurement powers, governments can provide clear market signals, allowing British-based firms like Bombardier, whose plant in Derby I have also recently visited, to develop the capabilities needed to win public contracts. Public contracts can be used, after all, to advance public goals: to train apprenticeships, to encourage innovation, and to boost local employment.

Baroness Thatcher’s passing has revived strong memories of a bygone era. Yes, she changed Britain, but changed circumstances mean our country’s economy now needs something different too - there is an alternative and we must grasp 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.
