Facetiming (?) the kids from St Pancras Station, and David Cameron walks into the back of the shot. I say ‘Good morning’, he says it right back. Nice enough chap, but a series of giveaway policies aren’t what we need, I think.

His right to buy policy takes us back to the eighties. Thatcher sorted out manufacturing, but only by wrecking it. We need people who can make things: take materials and add value through creativity, design and manufacture.

I spent a pleasant hour (once everyone had gone home) sketching a workshop in the excellent Smiths of Derby. Their bespoke clock making and restoring business is highly specialist but the skills needed are fantastically diverse, and hence there’s diversity in the people employed too. Smiths would get my vote.

Earlier in the week I ran 10 miles around Edinburgh and watched a motorcyclist with less interesting work to do than either Smiths or Dave are faced with.
