Nick Clegg: I was only aware of "indirect and non-specific concerns" about Lord Rennard

The Deputy Prime Minister reveals his involvement in the Rennard investigation.

Nick Clegg has admitted that he was aware of general concerns about behaviour of the party's former chief executive Lord Rennard, but has denied that he knew of specific allegations of sexual harassment.

"When indirect and non-specific concerns about Chris Rennard’s conduct reached my office in 2008, we acted to deal with them," said Clegg. But he did not know of the specific allegations until "until Channel 4 informed the party of them" when it broke the news last Thursday.

Clegg also attacked attempts to use the scandal to slight the party over all, saying "I will not stand by and allow my party to be subject to a show trial of innuendo, half-truths and slurs".

Clegg's statement follows that of his deputy, Vince Cable. Cable said he "absolutely" did not know of what he described as "serious" allegations. Jo Swinson MP says she "took action" after several party members shared concerns, but hasn't clarified what that action was.

Lord Renard himself has released a statement saying that he is "deeply shocked", and "strongly disputes" the claims made against him.

The full statement reads as follows:

The allegations made on Channel 4 concerning Lord Rennard last Thursday were extremely serious and distressing to the women involved. It is critical they are investigated thoroughly and dealt with properly and they will be.

But I would like to make one thing crystal clear. I did not know about these allegations until Channel 4 informed the party of them shortly before they were broadcast. I have today spoken to one of the women in the broadcast who I respect and admire and who confirmed that she had never raised the issue with me.

I am angry and outraged at the suggestion that I would not have acted if these allegations had been put to me. Indeed, when indirect and non-specific concerns about Chris Rennard’s conduct reached my office in 2008, we acted to deal with them.

My Chief of Staff at the time, Danny Alexander, put these concerns to Chris Rennard and warned him that any such behaviour was wholly unacceptable. Chris Rennard categorically denied that he had behaved inappropriately and he continues to do so. He subsequently resigned as Chief Executive on health grounds.

As my office only received concerns indirectly and anonymously, as those involved understandably wanted to maintain their privacy, there was a limit to how we could take this matter forward following Chris Rennard’s resignation. It is incorrect to state that there was any other separate inquiry by my office or anybody in it.

I recognise from the Channel 4 broadcast that there are legitimate concerns that issues raised with the party were not handled as well as they should have been. In particular the suggestion that a complaint was made but was not dealt with as a formal complaint. I am therefore determined that we carry out a thorough investigation into our procedures and how we applied them at the time to ensure we have a full and clear picture of what happened and the lessons that we need to learn. This review will be independently chaired.

A separate investigation into the specific allegations about Lord Rennard will take place under our disciplinary procedure. It is essential that this is carried out with due process and for that reason I cannot provide a running commentary on it. But I am absolutely determined that both these investigations will be carried out thoroughly and comprehensively. These investigations may well reveal flawed procedures, and clearly the women concerned feel they were not properly listened to. But I totally reject the insidious suggestion that my office or I are responsible in any way for a deliberate cover up.

The full truth of what happened and what failed to happen and who said what to whom will be revealed by these investigations.

But in the meantime, I will not stand by and allow my party to be subject to a show trial of innuendo, half-truths and slurs. The important thing is that we respect the women who have come forward and do everything to get to the truth. That is what will now happen.

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.
