What the Liberal Democrats should do next

Why yesterday's electoral disaster is not the end.

The left is generally more interested in protest than power. And so, even though in terms of practical policy the Liberal Democrats are ensuring that the coalition government is far less brutal than it otherwise would be, many on the left are gleeful at the party's electoral rout yesterday.

This is rather strange in terms of practical politics. It is almost as if the left wants the Conservatives to have more influence in the coalition, so as to punish Clegg and his party for daring to try to make a coalition work. The left seems to want the Conservatives to marginalise the Liberal Democrats in government. The left may well dislike the Tories; but they really do hate the ministerial Liberal Democrats, just as a religious fanatic hates the apostate more than the infidel.

This ferocity must bewilder and unsettle the average Liberal Democrat activist. They are more used to benefiting from the dislike voters have for the main two parties, rather than being disliked themselves. However, it may be that yesterday's electoral disaster, and the underlying antipathy which many now have for the party, has a silver lining.

If the Liberal Democrats are to be a serious party in respect of central government, there are two things to be done. First, they need to be more realistic and consistent in what they campaign for: manifestos and pledges now need to practical and attainable. The luxury of striking populist poses is for politicians in opposition, not those who actually have to implement policy. One hopes the Liberal Democrat MPs who made the pledge not to raise tuition fees and then voted to do so have learned this lesson.

Second, the party has to be distinct. As this blog has said previously, the blurring of lines between Tories and Liberal Democrats makes one want to adapt the ending of Animal Farm:

"The voters outside looked from Tory to Clegg, and from Clegg to Tory, and from Tory to Clegg again; but already it was impossible to say which was which."

The Liberal Democrats in the coalition need to emphasise differences with the Conservatives. Clegg should ration his appearances alongside Cameron. One realises it is perhaps not practical politics for the Liberal Democrats to go into opposition and offer their support on a vote-by-vote basis (though there is no constitutional or legal reason why they cannot); but it is crucial that the party develops a ministerial reputation separate from that of the Conservatives.

Both the Conservative and Labour Parties have come back from setbacks similar to that suffered by the Liberal Democrats yesterday. The loss of so many local councils will of course have an adverse and lingering effect on the party's activist base.

But it is not the end. Instead, it is a signal to the party that it has to take exercising and retaining ministerial power seriously; to think and act and campaign as a left-of-centre party of power, making a substantive and positive difference to actual policy. And then the self-indulgence of opposition for its own sake can be left to the Labour party.

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.
