Listeners to Radio 4’s Dead Ringers will be familiar with the caricature drawn of David Davis – the self-styled “Brexit Bulldog”. A minister patriotically and publicly straining at Theresa May’s leash to defend the UK’s interests in a dog fight against the rest of the EU. It’s a funny, well-executed, if crude, portrait.If Mr Davis is the bulldog, then Business Secretary Greg Clark is the Brexit badger. Not normally seen in public but busy under cover – padding between the boardrooms of businesses here and abroad to reassure them that investing in the UK is a good idea and all will be well in the end. That is not an easy brief with Brexit looming and negotiations making little, if any, substantial progress to date.And yet, Mr Clark has scored some memorable wins. In the weeks after the referendum vote, he managed to persuade a wavering Nissan to build not one, but two new models in Sunderland – securing 7,000 jobs for the carmaking industry.I can report that the mood music from insiders in the pharmaceutical industry has turned from decidedly anxious to cautiously optimistic about the future. How has he managed it? And perhaps more importantly, can he keep it up as the Brexit clock ticks down with dwindling chances of trade talks this side of Christmas?Industrial Strategy: Everyone hears talk of the “industrial strategy”, but very few people seem to know what those words mean.Government officials and civil servants talk about it as “an approach” to be understood, rather than a document to be read. So I sat down with Mr Clark – its author or architect – to achieve enlightenment. The first thing to understand, he said, is that it’s about more than dishing out government money.To take the car industry as an example. There was a bit of money put into battery development but there was also a collaboration with Formula 1’s testing facilities around Northampton, permission to use public roads to test self-driving cars, funding for a research facility in Warwick and a commitment to review and explore the law around any insurance issues that may present themselves. “Most of the investment always will come from the industry itself,” said Mr Clark. “What I am determined to do is to give the confidence that this is the right place to invest, because we are creating an environment for the future that is going to be the best in the world for some of these big new technologies.”The government intervention in pharmaceuticals and life sciences follows a similar blueprint – £146m to invest in several high tech programmes around the country, getting the University of Birmingham involved and a commitment to use the NHS as a test track for some of the industry’s newest medicines.The strategy is to pick an industry that the UK is already good at and needs investment. Chuck in a bit of government money, cluster the right institutions around it, commit to provide the skills base and give them somewhere to try their new stuff. Bingo – private investment will flood in.Fading optimism: Both Mr Clark himself and his approach are popular in the business world. I’ve heard him variously described as “bright”, “thoughtful”, “a good listener for a politician” and “hard-working”.But for all that, the evidence that the strategy itself is working is mixed. In fact, the investment numbers for the car industry in particular are very worrying.According to the Society of Motor Manufacturers and Traders, investment in the automotive industry has fallen from £2.6bn in 2015, £1.7bn in 2016 and just £322m for the first six months of this year. That’s a massive 75% fall in two years.However, Clark said: “The Engineer’s Employers Confederation have reported a rise in confidence. You have to remember that automotive investment is very lumpy. It comes in big chunks.”He needs another big chunk soon.The initial optimism has begun to fade with even Nissan’s Carlos Ghosn threatening to reconsider future investments if frictionless trade is not secured. All eyes are now on what the new part-French owners of Vauxhall (PSA Citroen) decide to do with Ellesmere Port and Luton. As a minister, it is hard to reassure businesses when you can’t tell them what the trading relationship will be between both their nearest, biggest and richest market and most of their supply chain.
