Cameron says "renegotiation", Conservative MPs hear "exit"

The Prime Minister's European strategy relies on an act of persuasion that he has proved himself incapable of pulling off.

No-one needs any more evidence that many Tory MPs don’t trust what their leader when he says when it comes to the European Union (or much else). If they did, they would have accepted his pledge in January that a referendum would be held in 2017, once the terms of British membership of the club have been renegotiated - and presuming Cameron is still prime minister after the next election.

But Conservative MPs have found that a Cameron promise doesn’t impress Ukip-minded voters on the doorstep and they struggle to defend their leader’s pledge-keeping credentials. (Members of the PM's entourage calling the activist base "swivel-eyed loons" is not going to quickly thaw relations between the leadership and the grass roots.) Hence the insistence on a bill this side of an election, restating the determination to put EU membership up for a national vote. Number 10 agreed to back such a move out of desperation to prove that the Prime Minister meant what he said back in January.

And no doubt he did. But there are two parts to Cameron’s EU strategy. The referendum is supposed to follow the renegotiation. Much more media coverage and political energy has been consumed on the promise of a vote than on the practicality of getting a good deal out of Britain’s European partners. It is worth noting, for example, that Nigel Lawson’s recent intervention on the subject attracted a great deal of attention because he said he would vote to quit the EU. Less remarked upon was the reason he gave as to why he can be so sure of that decision already. He doesn’t think renegotiation will work. And he’s right.

As I’ve written before, it is almost impossible to imagine Cameron securing a compromise on the UK’s current level of European integration that would satisfy his party because, almost by definition, compromise in Brussels is perceived as capitulation. The EU exists to facilitate cross-border collaboration at a political and not just an economic level and that process is what affronts the sensibilities of the sceptics.

I offer here one modest proof of how phenomenally hard it will be for Cameron to concoct a European settlement to satisfy his members. Writing in the Times last week, Robert Halfon, MP for Harlow in Essex, got stuck into the big oil companies for alleged price fixing. Halfon is a very effective constituency MP, a clever man and a popular figure on the Tory benches. He has been very influential in pushing the sensible idea that Conservatives should be focused on the cost of living and addressing more directly the concerns of working and lower-middle-class voters. He has campaigned on the issue of fuel costs with considerable success. He is respected on both sides of parliament. So what does this have to do with Europe? Halfon explains half-way through the piece:

We need regulators who are hungry for justice, and who have the right powers to pursue it. The Office of Fair Trading should have been pushing the European Commission to investigate, rather than holding last year’s spineless inquiry that came to almost no useful conclusions. Real EU renegotiation would mean bringing these investigatory powers back to Britain.

Halfon is dismayed that British competition authorities appeared to be asleep on the job, leaving it up to the European Commission to get tough on the oil giants. His solution is the repatriation of powers from Brussels. As far as I am aware this doesn’t appear on any list of realistic demands that Cameron might make of his European partners. The UK is subject to European competition law because we are in a single market and because British businesses want a level playing field when trading or merging with businesses in other countries and acquiring assets there. Even if we left the EU, British enterprises that wanted to engage in international commerce would comply with European competition law.

If Tory MPs want the OFT and the UK competition commission (which are in the process of being combined) to be tougher, are they supposed to be more rigorous in the enforcement of European rules? That is a question of greater zeal not repatriation of powers? Or are they supposed to apply some different, yet-to-be-drafted laws? In that case UK companies operating in the rest of Europe would have to comply with two sets of rules instead of one?

But the whole question is purely academic. Cameron will not put powers of competition regulation on his list of things to bring home from Brussels. He knows – if indeed he’s thought about it at all – that it can’t be done. So when Halfon says “real EU renegotiation” he means “impossible, fantasy renegotiation.” Or, put another way, by “renegotiation” he means “exit.” That is what most Tories now seem to mean by renegotiation.

The message from the Conservative party to their leader is clear. There is really nothing he can practically do or say that will persuade them to vote “yes” to the question of whether Britain should remain in the EU. Yet Cameron’s entire strategy hinges on accomplishing that act of persuasion.

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.
