The coalition is still failing business

The government's enterprise bill provides no evidence of a clear strategic direction.

Today the Enterprise and Regulatory Reform Bill receives its second reading in the House of Commons.  It was trailed in the days before the Queen’s Speech as the centrepiece of a legislative programme by the government built on “growth, justice and constitutional reform”.  In reality, it is anything but.

The bill is a good illustration of the weaknesses and divisions at the heart of the government. The most pressing issue facing Britain is the fact that the economy has gone into reverse. The Prime Minister and Chancellor may wish to hide behind the fact that there is a eurozone crisis, or that we had too many days off because of the Queen’s diamond jubilee, or that the weather is slightly too cold or too hot, or – at the moment – too much rain. But everyone else seems to realise, with the exception of the occupants of 10 and 11 Downing Street, that their insistence on cutting spending and raising taxes too far and too fast, and thereby choking off demand in the domestic economy, has plunged this country back into a recession made in Downing Street. What we need is a proper plan for jobs and growth to get the economy going again – like Labour’s five-point plan.

Only in the last few days, President Obama has implicitly criticised the government’s stance, noting that it is a lot harder to rein in deficits and debt if your economy is not growing.  Tellingly, he singled out Angela Merkel and François Hollande for “working to put in place a growth agenda alongside responsible fiscal plans”. No such praise for David Cameron or George Osborne.

There is no magic piece of legislation that would conjure up growth. But the case for a British Investment Bank needs to be examined, as Labour is doing.  Reforms to allow firms to better plan for the long-term, invest in new plant and skills and ensuring that there are more, better paid jobs so the economy works for more people, more of the time would also improve Britain’s competitiveness and allow us to get back into growth much more quickly.

In the longer-term, the bill provides no evidence of a clear strategic direction.  Business is crying out for a stable policy environment to allow them to invest and plan for the long-term; a proper industrial strategy, based on the long-term to encourage sustainable growth, but this bill has failed to provide this.

We have in the bill the establishment of the Green Investment Bank, a welcome initiative that Labour announced back in 2010, but it won’t have powers to lever in private money to boost green investment until 2016. 

There are reforms designed to make executive pay more accountable and transparent, but ministers are refusing to implement all of the sensible recommendations from the High Pay Commission such as putting an employee representative on remuneration committees – and now it appears that Vince Cable is seeking to water down provisions for annual shareholder votes on executive pay.

The bill includes reforms to employment legislation. There are some changes on tribunals which are worth exploring but, in a nod and a wink to the Tory right, the government is hinting that it could bring forward amendments during the bill’s passage to put Beecroft’s fire at will manifesto on the statute book, alongside other proposals within the bill to water down the rights we enjoy at work.

Cable lamented in his leaked letter to the Prime Minister that the government has lacked a compelling vision on where it wants to take the country’s economy by 2020.  With this bill had an opportunity to rectify this and provide the strategic vision which British business is crying out for, leaving a lasting legacy that would boost economic recovery and secure Britain’s competitiveness in the next decade. Faced with the roadblocks to reform in Downing Street, it is a great shame this opportunity has been missed.

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.
