Unions: “Stop David, not Get Ed”

Despite gleeful howls from the right-wing press, it seems that the unions were more interested in st

The debate about the extent to which Ed Miliband owes his election victory to the unions is going to rumble on and on. Already, it's the most prominent detail of his election: for instance, the Telegraph's front-page story today ("New Labour is dead") features the phrase "Mr Miliband insisted he was his 'own man' and not in thrall to the unions, whose support gave him victory."

This morning, Alistair Darling was on the Today programme to talk about Labour's future economic policy, but instead found himself tackled by Sarah Montague on Ed Miliband's likely economic direction, given the manner of his election. Even Patrick Wintour's detailed and excellent analysis of the voting breakdown in today's Guardian concedes in its headline that "the unions had the last word".

The right-wing press is clearly going to enjoy attempting to undermine Ed Miliband as he attempts to take the Labour Party forward with references to his "thrall" to union barons and his lack of a democratic mandate. There can be no doubt that the numbers appear to stack up behind this argument: Ed received first preferences from just 72 of the 635 constituency parties, but dominated union members, with 47,439 first preferences compared to his brother's 21,778. Union turnout overall was low -- just 9 per cent of those eligible voted -- but it seems that those who did turn out did so overwhelmingly for the younger Miliband.

The relationship between Labour and the unions must and should be subject to close scrutiny. But, before anyone writes Ed off as a union stooge, Kevin Maguire, in his Mirror column today, teases out a vital point: the unions didn't so much elect Ed Miliband as not elect David Miliband. Or, as Maguire put it, they "whirred into action to Stop David not Get Ed".

Nigel Morris in today's Independent makes a similar point, even quoting a union official saying: "We stopped David -- that's the main thing." According to another of Morris's union sources, they viewed their tactics as "levelling the playing field" for the other candidates in the face of David's superior resources.

And here we run up against yet another ramification of the Miliband brothers' family relationship -- in another contest, perhaps the way for Ed Miliband to distance himself from his apparent popularity with the unions would have been to emphasise that he had merely benefited from his rival's inability to appear "in touch" with the working class as represented by union members.

But although Ed has shown himself to be ruthless, he has also proved himself the kind of politician who will not kick a fellow candidate when he's down. That the candidate in question happens to be his elder brother would thus seem to rule this course of action out for him.

The problem now facing Ed Miliband is clear: if he takes union funding to replenish his party's empty coffers, making various concessions on his approach to cutting the deficit in return, the party will be financially ready to campaign much sooner. But, as the reactions from the right-wing press have already demonstrated, the taint of union involvement, especially when it comes to economic policy, hands crucial ammunition to the Conservatives at a time when Labour desperately needs to be on the offensive.

As delighted as Ed will be to have woken up leader of the Labour Party this morning, I can't help but think he will already be regretting, in private, how he got there.

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.
