Is Sky News biased against Labour?

No, is the short answer. Balls and Prescott are wrong.

During my period as a producer at Sky News, between 2005 and 2007, I used to answer the question, "Where do you work?" from members of my wife's family in the United States with the line: "A channel called Sky News. It's the British equivalent of Fox News."

What I meant, of course, was that Sky News is, like Fox News, a 24-hour rolling news channel, available on satellite and via cable, and part of Rupert Murdoch's global media empire. But in style and in substance, of course, it is nothing like the pro-war, pro-Republican, pro-Palin Fox News Channel (FNC).

For a start, we have Ofcom (which the Tories want to abolish!) and Ofcom would never allow such blatant, on-air bias in this country (God bless Ofcom!). Indeed, I defy you to find me a single anchor or reporter on Sky News who bears even a passing ideological resemblance to Bill O'Reilly, Glenn Beck or Sean Hannity.

But the Labour Party and some of its more credulous supporters seem to be insinuating -- or, in the case of Ed Balls and John Prescott, explicitly claiming -- that Sky News has a pro-Tory, anti-Labour bias.

Here's what the Children's Secretary said to me in his constituency on Saturday:

I travel to Yorkshire on the day the Guardian has endorsed the Liberal Democrats and the Times the Conservatives. Are the media united against a Labour victory? "The BBC has fought valiantly to be fair and balanced, but Sky News and most of the newspapers are deeply partisan." He criticises the Murdoch-owned broadcaster and the right-wing press again later in the interview. "This election is much more open than the newspapers and Sky News suggest. The polls are very tight."

And here is John Prescott, on the Guardian's Comment is Free, in the immediate wake of "Bigotgate":

Yet again, the dying Murdoch empire is doing all it can to influence a British election . . . But today, the Murdoch family reached a new low in their desperate attempt to turn the election for the Tories. News International's Sky News broadcast a private conversation between Gordon and his staff . . . What Murdoch's Sky News did today was just as bad as his paper's phone-hacking. It was a breach of privacy. It was underhand. And it was done in the pursuit of ratings and political influence.

This is absurd. Yes, Sky News broadcast the conversation in "pursuit of ratings". That's a given. And, I should add, you could argue that there was also a genuine public interest defence. Also, does anyone honestly believe ITV News wouldn't have done the same?

But to accuse Sky News of pursuing "political influence" is a desperate claim. There is no evidence whatsoever to suggest there is a co-ordinated anti-Labour, pro-Conservative campaign on the part of Sky News. John Ryley, the Sky News boss, Chris Birkett, his executive editor, and Jonathan Levy, the head of the broadcaster's political unit in Millbank -- all of whom I consider friends of mine -- are not Tories, and, if they are, they've done a damn fine job of hiding it from me and countless others.

Adam Boulton, meanwhile, is the semi-sympathetic biographer of Tony Blair -- and married to Blair's former "gatekeeper", Anji Hunter. Oh, and to those of you who have never worked in a TV newsroom, let me be very clear: Rupert Murdoch doesn't ring up each evening to discuss and decide the running orders with Messrs Ryley and Birkett. In fact, in my two years at Sky News HQ in Isleworth, Middlesex, Murdoch Sr physically turned up just once -- and, that too, to open a new building, not to pontificate on day-to-day editorial matters.

Labour critics of Sky News might point to last night's events at Methodist Central Hall, where Gordon Brown gave perhaps the best speech of the campaign so far, while Sky News chose to cover the lone anti-nuclear protester, rather than the speech itself and the impressive performance from the PM. It was a bad decision -- but again, in my view, this reflects Sky's sensationalist and perhaps understandable desire for ratings, upsets, gaffes and "incidents", rather than an explicit, pre-planned, anti-Brown agenda.

Left-wing conspiracy theorists can sleep in peace. The Sun is fighting a partisan, pro-Cameron, ant-Brown campaign. So, too, is the Times, with its propagandistic picture of Sam Cam lying in Dave's arms on its front page today. But Sky News remains, as far as I can see, free of party political bias.

All you could accuse it of -- maybe! -- is being part of a wider British press pack that has gullibly, lazily and perhaps subconsciously bought David Cameron's guff about change, momentum and inevitablility. If that's the case, the the BBC is equally guilty. But I repeat: Sky News is not the Sun. To compare the two is just silly.

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.
