Europe is still a Tory obsession. Labour should leave them to it

The next election will be decided by the economy, not by which party is the most eurosceptic.

David Cameron had a good day on Wednesday. After giving a convincing and impressive sounding speech that made him sound pragmatic and engaged with reforming the EU but also dangled the promise of an 'in/out' referendum within the next five years, he offered more than enough to pacify both the pro and anti-European wings of his party. In just over 25 minutes, he apparently managed what no Conservative leader could do in 25 years.                                                                                                                                                                                           
 
The Prime Minister will continue to get a good press and Labour, whose poll lead over the Tories had already narrowed to 5 points according to the latest ICM survey, will take some flak for not matching Cameron's promise of a referendum. Labour's handful of eurosceptics, and opportunist pundits who never think more than a few weeks ahead, will accuse Ed Miliband of dropping the ball.
 
But Miliband is wise to be cautious. The next election is a political lifetime away - 2017 is further still. If the wind changes decisively in the two and a half years between now and the 2015 election, there is plenty of time to perform a U-turn and back a public vote. As Cameron found to his cost after he promised and then reneged on a referendum on the Lisbon Treaty, there is no value in putting yourself at the mercy of uncontrollable events. 
 
In any case, jumping on the referendum bandwagon now would smack of the cynicism that it is. Labour cannot really expect people to buy into the pretence that it is more eurosceptic than the Tories.
 
The eruption of Tory support for their leader will be disconcerting for the Labour and Lib Dem benches, but we've been here before. The last time Cameron got such rapturous support from his party was his non-veto of the fiscal compact in December 2011. Conservative MPs lined up to praise their leader for standing up to Merkel and Sarkozy before realising that Cameron hadn't actually prevented anything.
 
Besides, it's easy to forget that, only a few days ago, Conservatives were at daggers drawn with each other over what Cameron should and shouldn't say. The speech has applied plenty of sticking-plaster but ensured that the next four years will be dominated by the European obsession that has afflicted the Tory party for the last twenty years. The Conservative Party's own European unity will cease as soon as the negotiations start. There's no need for Labour to start intruding into their private grief.
 
The other point is to look at who some of the most vocal Tory supporters of the speech are: Bill Cash, Douglas Carswell and Bernard Jenkin, all of whom will only vote for Britain to leave the EU. Around 100 Tory MPs would campaign for a 'no' vote regardless of what Cameron can secure from the rest of Europe. 
 
Cameron is more likely to have created a trap for himself, rather than for Labour. The notion that politicians in Berlin, Paris, Rome and elsewhere are going to offer a package of opt-outs and exemptions to satisfy the most eurosceptic wing of the Tory party lacks credibility. At best, Cameron will probably, like Harold Wilson in 1975, come home with little more than a piece of paper. Perhaps further powers for national parliaments in scrutinising EU legislation, an exemption from the Working Time Directive (which many countries don't enforce anyway), a protocol about border control, tighter democratic controls over the European Commission - which would probably be supported by all parties. Achieving even this short list would be quite a feat but Tory backbenchers would still accuse him of a sell-out.
 
In truth, there is a good chance that Cameron will not even get the chance to renegotiate. Changing the treaties would require the unanimous consent of all 26 other countries and an intergovernmental conference. Nobody wants to re-open the treaties unless they have to and, with the eurozone now looking stronger, the prospect of rewriting the treaties to protect the single currency is growing more remote. Indeed, although it had been widely assumed that deeper integration of the eurozone would lead to treaty reform, Merkel has signalled that she will not push for any changes to the EU treaties in the near future. The banking union legislation falls under the existing legal framework, while plans to create a mutualised debt market and single finance minister for the eurozone, which would require treaty change, are now on the backburner.
 
Conservative party supporters up and down the country will have the bunting out over the weekend, but most voters will soon forget about Cameron's referendum promise. The next election will be decided by the economy, not by which party is the most eurosceptic. And while the Tories may think that they can force Ed Miliband onto the back foot, nobody should forget the fact that the Prime Minister made this speech not because he wanted to, but because he felt he had to.

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.
