Paddy Ashdown and Ming Campbell take pre-conference swipes at Cable

Campbell tells Cable "don't be quite so gloomy" and Ashdown says that Clegg's enemy Lord Oakeshott is "Vince’s problem".

Nick Clegg and his allies have often privately expressed their frustration at how Vince Cable has sought (with some success) to avoid taking full responsibility for policies such as the tuition fees rise and the austerity programme by regularly positioning himself to the left of the coalition. But what is striking today is that two former Lib Dem leaders have gone public with their criticisms of the Business Secretary. In an article for the Guardian, ahead of the opening of the party's conference in Glasgow tomorrow, Ming Campbell writes: "And by the way Dr Cable, don't be quite so gloomy!" 

While recognising the importance of differentiating themselves from the Tories on the economy, the Lib Dems also want to take their share of the credit for the recovery. Cable's consciously downbeat assessment this week was widely viewed as unhelpful. 

In addition, following Lord Oakeshott's hackneyed call for the party to consider removing Clegg, Paddy Ashdown, the Lib Dem leader's political godfather, remarked: "I think Matthew’s self-appointed position as a sort of vicar on Earth for Vince does neither of them any good ... but that’s Vince’s problem". 

With these interventions, Campbell and Ashdown are rather kicking a kick at a man when's he down. A year ago, when Clegg's position still seemed at risk, Cable was viewed as the party's leader-in-waiting. He memorably signalled his interest in the position ("I don’t exclude it – who knows what might happen in the future...The worship of youth has diminished – perhaps generally – in recent years.") and was aided by a poll showing that the Lib Dems would gain four points with him as leader. But the Eastleigh by-election (which proved that the party could win in its strongholds) and the return of growth (which deflated Cable's call in the New Statesman for a plan B) mean that his star has waned. As I suggest in this week's NS, Tim Farron is now the man to watch.

The rise of the green mayor – Sadiq Khan and the politics of clean energy

At an event at Tate Modern, Sadiq Khan pledged to clean up London's act.

On Thursday night, deep in the bowls of Tate Modern’s turbine hall, London Mayor Sadiq Khan renewed his promise to make the capital a world leader in clean energy and air. Yet his focus was as much on people as power plants – in particular, the need for local authorities to lead where central governments will not.

Khan was there to introduce the screening of a new documentary, From the Ashes, about the demise of the American coal industry. As he noted, Britain continues to battle against the legacy of fossil fuels: “In London today we burn very little coal but we are facing new air pollution challenges brought about for different reasons." 

At a time when the world's leaders are struggling to keep international agreements on climate change afloat, what can mayors do? Khan has pledged to buy only hybrid and zero-emissions buses from next year, and is working towards London becoming a zero carbon city.

Khan has, of course, also gained heroic status for being a bête noire of climate-change-denier-in-chief Donald Trump. On the US president's withdrawal from the Paris Agreement, Khan quipped: “If only he had withdrawn from Twitter.” He had more favourable things to say about the former mayor of New York and climate change activist Michael Bloomberg, who Khan said hailed from “the second greatest city in the world.”

Yet behind his humour was a serious point. Local authorities are having to pick up where both countries' central governments are leaving a void – in improving our air and supporting renewable technology and jobs. Most concerning of all, perhaps, is the way that interest groups representing business are slashing away at the regulations which protect public health, and claiming it as a virtue.

In the UK, documents leaked to Greenpeace’s energy desk show that a government-backed initiative considered proposals for reducing EU rules on fire-safety on the very day of the Grenfell Tower fire. The director of this Red Tape Initiative, Nick Tyrone, told the Guardian that these proposals were rejected. Yet government attempts to water down other EU regulations, such as the energy efficiency directive, still stand.

In America, this blame-game is even more highly charged. Republicans have sworn to replace what they describe as Obama’s “war on coal” with a war on regulation. “I am taking historic steps to lift the restrictions on American energy, to reverse government intrusion, and to cancel job-killing regulations,” Trump announced in March. While he has vowed “to promote clean air and clear water,” he has almost simultaneously signed an order to unravel the Clean Water Rule.

This rhetoric is hurting the very people it claims to protect: miners. From the Ashes shows the many ways that the industry harms wider public health, from water contamination, to air pollution. It also makes a strong case that the American coal industry is in terminal decline, regardless of possibile interventions from government or carbon capture.

Charities like Bloomberg can only do so much to pick up the pieces. The foundation, which helped fund the film, now not only helps support job training programs in coal communities after the Trump administration pulled their funding, but in recent weeks it also promised $15m to UN efforts to tackle climate change – again to help cover Trump's withdrawal from Paris Agreement. “I'm a bit worried about how many cards we're going to have to keep adding to the end of the film”, joked Antha Williams, a Bloomberg representative at the screening, with gallows humour.

Hope also lies with local governments and mayors. The publication of the mayor’s own environment strategy is coming “soon”. Speaking in panel discussion after the film, his deputy mayor for environment and energy, Shirley Rodrigues, described the move to a cleaner future as "an inevitable transition".

Confronting the troubled legacies of our fossil fuel past will not be easy. "We have our own experiences here of our coal mining communities being devastated by the closure of their mines," said Khan. But clean air begins with clean politics; maintaining old ways at the price of health is not one any government must pay. 

'From The Ashes' will premiere on National Geograhpic in the United Kingdom at 9pm on Tuesday, June 27th.
