Ever noticed how shutting one door can open another? This week Labour's staunchest champion of growing our way out of the deficit acknowledged that he could well be making cuts in 2015. The left, personified by Owen Jones and Len McCluskey, were up in arms. They think we've lost the possibility of being radical. I say we've opened it up.

The modern left frequently makes one mistake. They assume that the most significant means government has of transforming lives is through taxing and spending, traditionally known as the "demand" side of the economy. They have left the supply side - the rules that govern the price of labour and capital - to the right.

But what if, at a time of pressure to reduce government spending, the left could develop an agenda for the supply side of the economy that delivered meaningful change?

It's not surprising we're sceptical. Because the right have dominated such policy in the past, such an agenda is associated with smashing unions to decrease the cost of labour, deregulating capital to enrich the fortunate or privatising at the expense of quality.

But supply side policy doesn't have to be regressive. It's just a tool that's been used in the wrong way. Most recently, Ed Miliband has been talking about a number of supply side policies that are courageous, imaginative and proudly consistent with the values of the left.

The most high profile example is his attack on certain energy and transport companies. We know that these markets are sown up, so increasing competition and regulation will deliver a fairer result. The living wage is another example. Government contracts that build in apprenticeships and local investment is another. The High Pay Commission's work on wage transparency and shareholder representation on boards is another. Cutting down on corporate tax havens as Miliband just outlined is another. Breaking up the banks takes this one step further.

Although it needs sexier branding, these supply side policies are all part of what Miliband calls "responsible capitalism". It's why Blue Labour is interesting.

These policies have three big advantages. First, they don't cost anything. Second, they make people's lives better. Third, they are much closer to where the public is at. I appreciate the arguments made by Owen Jones, but I don't think he has appreciated the scale of anger there is about a perceived waste of public money by Labour in the good times.

As someone who remembers what it was like to not have enough chairs in their classroom, I'm never going to apologise for investing in schools, and you'll never hear me say that government spending isn't essential and necessary. But waste on IT contracts, PFI and middle managers? I'm happy to apologise for some of that.

And as Ed Balls said this week, a true Keynesian is sometimes a hawk. If you genuinely believe we should be running a programme of increased spending now, then you have to acknowledge that we should have spent less when the economy was booming. The idea that Keynesians believe in high spending throughout the cycle misses the point completely.

So let's not get confused - Labour is still saying that we should cut less fast and less deep now, but with the OBR estimating we'll be 18 per cent poorer as a result of the recession, the state will be smaller once we're out of this mess. And that means a progressive supply side agenda.

If we do that, then Ball's speech wasn't a sign of giving up and following the Tories slowly back to the middle ground. It was a necessary part of gaining credibility with the public to make way for a new agenda that is profoundly exciting. Interestingly, it's one that Miliband is leading, not the shadow chancellor. The left shouldn't abandon ship, it should get on board.

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.
