Governments in Britain since Mrs Thatcher’s time have refused to have an industrial strategy and, as a result, we have very little industry left. McKinsey in a study a few years ago said that although roughly one pound in eight of our national income still came from manufacturing, only about a quarter of this was genuinely competitive in international markets — the science-based engineering from aerospace, defence and the North Sea, the innovation from pharmaceuticals and computing (plus a few other products with Scotch Whisky being the most obvious and lucrative) — which were unique to this country but with international appeal.
