Lord Oakeshott resigns from the Lib Dems over leaked Clegg poll

Peer leaves the party and warns it is "heading for disaster" under Clegg.

After Nick Clegg warned this morning that "appropriate steps" would be taken against Lord Oakeshott for leaking a poll that suggested he would lose his seat, the Lib Dem peer has just resigned his membership of the party. You can read his statement in full below.

Of note is that Oakeshott has dragged his old ally Vince Cable, who condemned his actions last night, back into the affair. He reveals that a few weeks ago he told Cable the results of the four constituency polls (including that in Clegg's seat) that appeared in the Guardian. Cable can argue that he did not commission the polls and that he did not know they were going to be leaked (while also noting that he removed a leadership question from a poll of his Twickenham consttuency). But if, as seems likely, he hid the results from Clegg, his reputation will be damaged.

I am today taking leave of absence from the House of Lords and resigning as a member of the Liberal Democrats. I am sure the Party is heading for disaster if it keeps Nick Clegg; and I must not get in the way of the many brave Liberal Democrats fighting for change.

I leave, with a heavy heart, the party I helped to found with such high hopes with Roy Jenkins, Bill Rodgers, Shirley Williams and David Owen at Limehouse in 1981. We then, like most Liberal Democrats now, wanted a radical progressive party, not a “split the difference” Centre Party, with, in Shirley’s memorable words, no roots, no principles and no values. But that is where Nick Clegg has led us.

I am sorry I have so upset and embarrassed my old friend Vince Cable and that we were not able to talk before he issued yesterday’s statement from China. This is the background:

Several months ago a close colleague, concerned about voting intentions in Twickenham, asked me if I would arrange and pay for a poll to show us Vince’s current position and how best to get him re-elected. I was happy to help, and Vince amended and approved the questionnaire, but at his request I excluded a question on voting intentions with a change of leader. Although Vince had excellent ratings, both as a Minister and a local MP, he was slightly behind the Conservatives in this poll, as the full details on the ICM website (http://www.icmresearch.com/) show. That poll worried me so much that I commissioned four more in different types of constituency all over the country and added back the change of leadership question. The results were in the Guardian yesterday and on the ICM website (http://www.icmresearch.com/media-centre/polls/lib-dem-constituency-polling). Several weeks ago, I told Vince the results of those four polls too.

The combined message of these five professional and reputable ICM constituency polls, Nick Clegg’s dire approval ratings year after year in all national polls, and Thursday’s appalling council and European election results is crystal clear: we must change the leader to give Liberal Democrat M.P.s their best chance to win in 2015. On Thursday I also commissioned one more ICM poll, in Inverness, Nairn, Badenoch and Strathspey; the results should also be on the ICM website tonight at http://www.icmresearch.com/data/media/pdf/2014_libdems_inverness.pdf and http://www.icmresearch.com/data/media/pdf/2014_twick.pdf

A few stout-hearted M.P.s and peers and hundreds, maybe soon thousands, of candidates, councillors and Lib Dem members all over Britain are now fighting constituency by constituency for a leadership election. I have tried to give them the evidence they need to make the change. I pray that they win, and that the right man, or preferably, woman is now elected to save the Party.

When Charles Kennedy rang to make me a peer, from a panel elected by the party, fourteen years ago he said he wanted me to shake up the Lords. I’ve tried - my bills to ban non-dom peers are now law – but my efforts to expose and end cash for peerages in all parties, including our own, and help get the Lords elected have failed. I am very sorry to leave my many old, close comrades-in-arms on the Liberal Democrat benches all over Britain, and good friends and fellow campaigners across the House. But the unreformed Lords is now a bloated balloon and at 67 it’s time to concentrate on running my business and my charity.am today taking leave of absence from the House of Lords and resigning as a member of the Liberal Democrats. I am sure the Party is heading for disaster if it keeps Nick Clegg; and I must not get in the way of the many brave Liberal Democrats fighting for change.

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.
