I’ve always wondered what happened to the framed tenner hanging on the wall of the Rover Group boardroom, inside the Longbridge complex where, in former times, Alec Issigonis perfected the Mini.

As we reach the 20th anniversary of the infamous deal done between Rover’s then-owner BMW and the four British managers who came up with a plan to buy it for £10 and operate it, aka the Phoenix Four, I wonder this even more.

Clearly, that framed tenner wasn’t the actual unit of currency paid for the company. BMW had presumably already received that. This was a symbolic tenner, hung in their new wood-panelled management lair by John Towers, Nick Stephenson, Peter Beales and John Edwards, both to impress stray passers-by like me and as a private reminder of their extraordinary management coup.
