Labour’s five steps to tackle tax avoidance

David Cameron has failed to bring forward the changes which are needed to bring transparency. Labour would develop a robust and effective corporation tax system.

In tough times it’s more important than ever that everyone plays their part and pays their fair share of tax.

People and businesses who pay their fair share have been shocked by how little tax some companies seem to pay in Britain. Sometimes there are good reasons why, such as because they are investing in research and development. But all too often companies that pay low taxes in Britain are doing so because they can bend the rules to their advantage.

As Ed Miliband says in his interview with today’s Observer, businesses need to act in a responsible way, but the government sets the rules of the game, so they too have a responsibility to act. David Cameron and George Osborne are not just cutting taxes for millionaires, they are also doing far too little to tackle tax avoidance. And they are pushing through deep cuts to HMRC, which risk being a false economy if they make it even harder to enforce the law. 

At the start of the year, we set down a challenge to the government: that they should end the era of tax secrecy. Some companies have not been paying their fair share of tax, hiding behind complex networks of companies and using tax havens to shift their profits out of tax. We said that the government needed to show leadership, bringing forward measures for the G8 that started with the requirement to publish a simple statement for the tax which companies pay in the UK.

But the government has failed to bring forward the changes which are needed to bring transparency. They have also failed to grasp the need to reform of the Corporate Tax system to close the loopholes which are being used by some companies.

This isn’t good enough. David Cameron must deliver real action at the G8 meeting next month, starting with Labour’s five steps to tackle tax avoidance:

i. Labour supports a form of country-by-country reporting. Agreed internationally it would mean large multinational companies should have to publish the key pieces of information which people need to properly assess the amount of tax they pay. This would cover their revenues, profits and taxes in each country that they operate. As well as meaning that multinational companies pay the right level of tax in the UK, this change would be a boost for developing countries. It would stop profits being stripped out from those countries, increasing their tax revenues and reducing their reliance on aid.

ii. Labour would extend the Disclosure of Tax Avoidance Schemes regime, which Labour introduced, to global transactions. The IF campaign have said this would be an effective way of tackling avoidance in developing countries.

iii. Labour would open up tax havens, with requirements to pass on information about money which is hidden behind front companies or trusts. Labour is backing the IF's campaign's calls for the UK to Launch a Convention on Tax Transparency at the G8 to deliver this.

iv. Labour will continue to challenge the government on the impact of their changes to Controlled Foreign Company Rules on the UK and developing countries. Labour has repeatedly tabled amendments in Parliament to introduce a proper assessment of the rules, which have been rejected by the government.

v. Labour also wants to see fundamental reform of the corporate tax system, because the shifting of profits and use of tax havens to avoid tax is also a symptom of a system which is failing to keep up with global economic developments.

That is why Labour is today publishing an update on its review into the full Corporation Tax system. The aim of Labour’s review is to develop a system which is robust and effective in the modern world; supports investment and job creation; deals effectively with the complexities of international business; is fair to all; and is transparent and can be better understood by the public.

Families and businesses who are paying their fair share want to see tax avoidance properly tackled. If David Cameron fails to deliver, then it will fall to the next Labour government to act.

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.
