About 30 years ago, I was in a pub in Sarf London, it was a leftish sort of reunion.

One of the "boozers" of honour was an old retired "Vickers" engineer, who had been one of those accused of sabotage in a "show Trial" over the sabotage of a USSR Hydro-electric scheme.

He had confessed, after presure, to putting nuts and bolts into a turbine. And was duely sentanced to death, commuted to life in Siberia, and released (British Citezen and Passport !!!)

His story on the "confession" was intersting - Basically of course he signed it, no arguments, on the grounds that it was so technically impossible that no fair court would have acepted it. - Like putting half inch (13 millimeter)debrise into the stream, up straem of the grids, filters and nozzels.

But for all that, still a "lefty".
