"Shared objectives", "illegal" briefings, and . . . Take That

What today's emails tell us about Jeremy Hunt and his relationship with News Corp.

After an explosive day, the Leveson Inquiry has published the email correspondence of News Corps’ top lobbyist, Frederic Michel, and it is not looking good for the Culture Secretary Jeremy Hunt. (You can read all 163 pages of it here).

First and foremost is the email dated 24th January 2011, quoted in today’s proceedings, in which Michel gets early warning about an announcement to be made by Hunt. Michel forwards it to James Murdoch saying:

Managed to get some infos on the plans for tomorrow (although absolutely illegal)

In the hearing, Murdoch defended this saying that the use of a winky face indicated that this was a joke.

Equally – if not more – damning, is an email sent the day before, in which Michel says that Hunt has stated that “he shared our objectives”:

He understands fully our concerns regarding the publication of the report and the consultation of Ofcom in the process; but he wants us to take the heat, with him, in the next 2 weeks.

He very specifically said that he was keen to get to the same outcome and wanted JRM to understand he needs to build build some political cover on the process.

If he were to follow our Option 1 and not provide any details on the Ofcom report, he would be accused of putting a deal together with ns behind closed doors and it would get in a much more difficult place. The more this gets out now, the better it will be as the opposition will lose arguments. This week’s events do not give him much choice.

He said we would get there at the end and he shared our objectives.

Finally, he asked us to stick with him in the coming weeks, plan the upcoming Tuesday’s publication and the debate which will unfold.

On a lighter note, an email sent to Hunt’s adviser Adam Smith on 7th June 2011 has raised some eyebrows. In it, Michel complains that his attempts to meet Ed Vaizey have been unsuccessful:

I tend to think that he could see us on specific policy items. We’re still involved in the media agenda even during the Sky deal.
It’s a very punitive decision ... I feel victimised :)

For example, I am working on our response for the open letter and it would have been great to discuss it with you before finalising it at some stage before end of June. Possible?

By the way, does that mean you and Jeremy will not be coming to Take That on the 4th July?

At the moment it looks like Hunt didn’t go to see the boyband’s reunion tour with News Corps. It is just as well really, as the scheduled date, 4th July, is when the Milly Dowler story broke. How is that for irony?

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.
