Don't want to get into a heavy political debate here, but from what I recall, when Mrs.Thatcher won the election in 1979, the unions were wielding far too much power in the country and the 'winter of discontent' just about characterised this.
I don't disagree with that - that was certainly a perception. What I was disagreeing with was HG's assertion that the 1975-79 Labour government left the country in economic chaos (and specfically had to be bailed out by the IMF). I'd say that the former wasn't true and the latter only partially so - I'm making no comment about the extent of union power but that was certainly a key factor in Thatcher's victory
