What do the unemployment figures actually show?

There was no good news in today's figures -- and this is just the beginning.

The awful unemployment numbers today came as no surprise to those of us who have been arguing these many months that George Osborne's economic strategy is disastrous for the British economy. There was never the slightest prospect of a expansionary fiscal contraction in the depths of a once-in-a-century financial crisis.

This is all likely to get a lot worse over the next few months. Unemployment rising, the number of jobs and total hours falling and rising unemployment durations. There was no good news.

David Cameron, master of understatement, admitted at PMQs today, at which he took a batterring over the economy, that the numbers were "disappointing". Indeed, Labour today accused Cameron of "bluster, evasion and untruths" in his attempt to defend what they called his "failing economic record". Liam Byrne, Labour's shadow work and pensions secretary, said:

David Cameron's complacency today was simply breathtaking. And, under pressure to explain why unemployment is rising and the economy flatlining, he once again resorted to bluster and evasion and got his figures badly wrong.

So what did the ONS data release actually show, rather than what the Prime Minister wished they showed?

1. An increase in ILO unemployment of 80,000 on the rolling May-July quarter, going over the 2.5 million mark. The unemployment rate remains at 7.9 per cent.

2. The more timely claimant count for August increased by 20,000.

3. There was a growth of 29,000 of discouraged workers, who were out of the labour force but reported that they wanted a job

4. Employment fell by 69,000 on the quarter but was up 24,000 on the year. Workforce jobs were down 100,000 on the quarter and down 41,000 on the year.

5. Public-sector jobs fell 111,000 on the quarter and 240,000 on the year, contrary to what Cameron falsely claimed at PMQs today. Private-sector jobs were up 41,000 on the quarter and 264, 000 on the year. This is approximately half the 500,000 jobs that Osborne recently claimed had been created under his watch. It is becoming clear, as we get more data, that most of the jobs created were under Darling's watch.

These numbers are set to worsen further and as each month goes by, it will become increasingly obvious that private-sector job creation is slowing fast. Time to own these numbers, George. Your policy is failing fast.

6. Hours picked up a little, but as I suggested in an earlier blog, the decline observed over the past couple of months was not just because of bank holidays, as David Smith recently claimed on his blog. Total hours were 914.3 million on the quarter, down from 921.3 million in May-July 2010 when the coalition took office.

7. Youth unemployment rose by 78,000 on the quarter to 973,000. Especially worrying was the rise of 35,000 of 18-to-24-year-olds on the quarter who had been unemployed for 12 months or more. The number of 18-to-24-year-olds on the claimant count for at least 12 months was also up on the month. Long duration unemployment is especially bad and shamefully, the government seems to have no policy to deal with this growing problem.

8. Wage pressure remains benign. Regular pay rose by 1.7 per cent on the month so, with inflation at 4.5 per cent, driven primarily by Osborne's VAT increase, most workers are having real pay cuts.

9. Scotland was the only region that saw falling unemployment on the quarter.

This is just the start of a flood of dreadful economic news that is expected to hit us over the next couple of months. The coalition government's economic strategy is in tatters.

Ed Balls and Ed Milband are going to have a field day with Natalie Rowe's -- aka Mistress Pain -- claims of Osborne's cocaine use and his interest in her work as a dominatrix. Talk of paddles, whips, chains and handcuffs are certainly not going to do much for his credibility, which is already in tatters as the economy tanks. Osborne's sneering is going to come back to haunt him. The Labour leader today suggested at PMQs that the Chancellor had "lashed himself to the mast. Not for the first time perhaps!"

Sadly, the coalition appears to believe that unemployment is a price worth paying. I suspect that the British people will have something to say about that.

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.
