Cable's most serious challenge yet to Cameron's authority: "Jeremiah was right"

The Business Secretary's repeated attacks on the Tories in his speech and his warnings of a new housing bubble meant it was easy to forget he is serving in the government at all.

There were moments in Vince Cable's speech to the Lib Dem conference where you had to pause to remind yourself that he is a serving member of the government, rather than an opposition politician. While Nick Clegg and Danny Alexander are focused on ensuring that the Lib Dems receive their share of the credit for the economic recovery, Cable cast himself as a Cassandra warning of a new and dangerous housing boom.

In the most striking passage of his speech, he declared that "there are already amber lights flashing to warn us of history repeating itself" and derided those (George Osborne) who would settle for "a short-term spurt of growth fuelled by old-fashioned property boom and bankers rediscovering their mojo". After David Cameron rather mildly remarked, "It's not right to cast Vince as a perpetual Jeremiah. He can brighten up from time to time", Cable pulled no punches in response, quipping that "David Cameron has called me a Jeremiah, but you’ll recall from your reading of the Old Testament that Jeremiah was right." He added: "He [Jeremiah] warned that Jerusalem would be overrun by the armies of Nebuchadnezzar.  In my own Book of Lamentations I described how Gordon Brown’s New Jerusalem was overrun by an army of estate agents, property speculators and bankers.

"The problem we have now is that the invaders are coming back.  They have a bridgehead in London and the south east of England. They must be stopped.  Instead we need sustainable growth."

Cable has never been a stirring platform orator and the response from delegates was more muted than in previous years but the speech was the most significant he has delivered since becoming Business Secretary. More than at any other point, he has gone exceeding the normal limits of collective responsibility.

While the speech opened with a recollection of the "unhealthy tribalism" and "Tammany Hall culture" that led him to resign from Labour in the 1970s (which he suggested had been reborn in Falkirk and other "Labour fiefdoms"), it was otherwise dominated by excoriating attacks on the Tories. He declared that "the nasty party" was back, with "dog whistle politics, orchestrated by an Australian Rottweiler.  Hostility towards organised labour, people on benefits and immigrant minorities." He rebuked his "cabinet colleagues" for "careless talk" about Britain leaving the EU and declared: "Let’s remember that we voted to join the present Coalition.  We did not vote to join a coalition with UKIP."

Elsewhere, in a rebuke to those on the right of the Lib Dems, such as Jeremy Browne and David Laws, seeking to push the party in a more free market direction, he warned that it was not enough to be "a nicer version of the Tories", again signalling his instinctive preference for Labour.

Ahead of 2015, the balancing act required of the Lib Dems is to differentiate themselves from the Tories without discrediting the government they have served in for more than three years. After Cable's unreserved attacks on the coalition's economic policies, Clegg will feel that the Business Secretary has failed in that task.

Debunking Boris Johnson's claim that energy bills will be lower if we leave the EU

Why the Brexiteers' energy policy is less power to the people and more electric shock.

Boris Johnson and Michael Gove have promised that they will end VAT on domestic energy bills if the country votes to leave in the EU referendum. This would save Britain £2bn, or "over £60" per household, they claimed in The Sun this morning.

They are right that this is not something that could be done without leaving the Union. But is such a promise responsible? Might Brexit in fact cost us much more in increased energy bills than an end to VAT could ever hope to save? Quite probably.

Let’s do the maths...

In 2014, the latest year for which figures are available, the UK imported 46 per cent of our total energy supply. Over 20 other countries helped us keep our lights on, from Russian coal to Norwegian gas. And according to Energy Secretary Amber Rudd, this trend is only set to continue (regardless of the potential for domestic fracking), thanks to our declining reserves of North Sea gas and oil.

The reliance on imports makes the UK highly vulnerable to fluctuations in the value of the pound: the lower its value, the more we have to pay for anything we import. This is a situation that could spell disaster in the case of a Brexit, with the Treasury estimating that a vote to leave could cause the pound to fall by 12 per cent.

So what does this mean for our energy bills? According to December’s figures from the Office of National Statistics, the average UK household spends £25.80 a week on gas, electricity and other fuels, which adds up to £35.7bn a year across the UK. And if roughly 45 per cent (£16.4bn) of that amount is based on imports, then a devaluation of the pound could cause their cost to rise 12 per cent – to £18.4bn.

This would represent a 5.6 per cent increase in our total spending on domestic energy, bringing the annual cost up to £37.7bn, and resulting in a £75 a year rise per average household. That’s £11 more than the Brexiteers have promised removing VAT would reduce bills by. 

This is a rough estimate – and adjustments would have to be made to account for the varying exchange rates of the countries we trade with, as well as the proportion of the energy imports that are allocated to domestic use – but it makes a start at holding Johnson and Gove’s latest figures to account.

Here are five other ways in which leaving the EU could risk soaring energy prices:

We would have less control over EU energy policy

A new report from Chatham House argues that the deeply integrated nature of the UK’s energy system means that we couldn’t simply switch-off the  relationship with the EU. “It would be neither possible nor desirable to ‘unplug’ the UK from Europe’s energy networks,” they argue. “A degree of continued adherence to EU market, environmental and governance rules would be inevitable.”

Exclusion from Europe’s Internal Energy Market could have a long-term negative impact

Secretary of State for Energy and Climate Change Amber Rudd said that a Brexit was likely to produce an “electric shock” for UK energy customers – with costs spiralling upwards “by at least half a billion pounds a year”. This claim was based on Vivid Economic’s report for the National Grid, which warned that if Britain was excluded from the IEM, the potential impact “could be up to £500m per year by the early 2020s”.

Brexit could make our energy supply less secure

Rudd has also stressed  the risks to energy security that a vote to Leave could entail. In a speech made last Thursday, she pointed her finger particularly in the direction of Vladamir Putin and his ability to bloc gas supplies to the UK: “As a bloc of 500 million people we have the power to force Putin’s hand. We can coordinate our response to a crisis.”

It could also choke investment into British energy infrastructure

£45bn was invested in Britain’s energy system from elsewhere in the EU in 2014. But the German industrial conglomerate Siemens, who makes hundreds of the turbines used the UK’s offshore windfarms, has warned that Brexit “could make the UK a less attractive place to do business”.

Petrol costs would also rise

The AA has warned that leaving the EU could cause petrol prices to rise by as much 19p a litre. That’s an extra £10 every time you fill up the family car. More cautious estimates, such as that from the RAC, still see pump prices rising by £2 per tank.

The EU is an invaluable ally in the fight against Climate Change

At a speech at a solar farm in Lincolnshire last Friday, Jeremy Corbyn argued that the need for co-orinated energy policy is now greater than ever “Climate change is one of the greatest fights of our generation and, at a time when the Government has scrapped funding for green projects, it is vital that we remain in the EU so we can keep accessing valuable funding streams to protect our environment.”

Corbyn’s statement builds upon those made by Green Party MEP, Keith Taylor, whose consultations with research groups have stressed the importance of maintaining the EU’s energy efficiency directive: “Outside the EU, the government’s zeal for deregulation will put a kibosh on the progress made on energy efficiency in Britain.”
