This is somewhat of a myth. The UK is currently in the top 10 manufacturing nations, and it’s worth £500bn

The biggest sector is engineering (half of all Ford diesel engines, Mini, JLR, Toyota, Nissan, Aston-Martin, Bentley, Rolls-Royce, Rolls-Royce, JCB, Siemens, Hitachi, BAE, Airbus, various defence companies). The only F1 team without UK engineering is Ferrari.

Pharma includes GSK and AstraZeneca, ships at Harland & Wolff and Cammell-Laird, high-end tech such as Sony film & broadcast equipment. Of course Henry.
