I watched Andrew Lloyd Webber’s Cats last night, via YouTube and The Show Must Go On.  I loved it – for its music, its singing, dancing, choreography, characterisation. The whole things knocked me out.

I’m taking it as my stepping-off point on a very different subject. From musical theatre to hard-core political theatre.

There’s a revealing short article, part of a feature on trade, by Liz Truss (Minister for Distant Rooftops) in the current edition of Prospect.

She highlights the many long international supply chains ‘with little resilience to shocks’. The answer is, she believes, ‘not isolation and self-sufficiency – neither of which are credible in the interdependent world we live in. Instead we should broaden our range of trading relationships, so we are not limited to just one country, bloc or continent. We can then begin to achieve the kind of diverse supply chains that will safeguard us against future crises.’

This is what you’d expect from one of the authors of that cheerful libertarian document, Britannia Unchained, and trailblazer of the dream world of Global Britain.

(I’m reminded of Dick Whittington, a cat from another time and place, seeking his fortune – but this time in China.)

I’d like to pitch against that, as a down-home example, Preston’s policy of prioritising local suppliers. Two radically different paradigms. Preston’s is compatible with global trading relationships. But not with a libertarian free-market paradigm, whereby you source the cheapest goods and services, regardless of origin. Boris Johnson has indeed singled-out Preston for back-handed praise: recognising its success but making it clear it isn’t the way forward for the country.

(Boris, our absentee prime minister: ‘Whatever time the deed took place,/Macavity wasn’t there!’ Only, in Boris’s case, he too often hasn’t been there in the first place.)

It should be self-evident, but sadly isn’t to the current Cabinet, that local and international need to work in tandem.

Diversified supply chains, even if they are achievable in Truss’s romanticised world, will not safeguard us against future crises. The further we reach beyond Europe, and the more we’re exposed to issues of distance and transport, and all the problems that arise from political and military conflict, the higher the levels of risk.

The latest edition of The Economist is on the same page, though not quite the same tack, as I am: ‘The pandemic will politicise travel and migration and entrench a bias towards self-reliance. This inward-looking lurch will enfeeble the recovery, leave the economy vulnerable and spread geopolitical instability.’

No-one is arguing against global trade. The reverse. Pursue it as hard as we can. But it’s essential we secure our base, and that is our local and national economies – and indeed European economies. That need not be ‘an inward-looking lurch’.

I shouldn’t push parallels with Cats too far. But – secure your own rooftop, then your wider patch. Don’t rely on Mr Mistoffelees, aka Dom Cummings, to magic your way out of trouble.

An obsession with global trade is especially bizarre from a government which secured its election on the basis of an appeal to the country’s insular instincts. But that’s taking us back to old arguments.

‘… a new day will begin,’ as Elaine Page sings. It won’t come the way we’re going now.
