I can't comment on Spanish history, but for me Wilson's resignation marks the end of the post-war ascent of the Left.

Callaghan's appalling term led directly to Thatcher, and now here we are, some thirty years later.

Carter's hostage-crisis set-up was also a very calculated and deliberate election fixer for Reagan, and even though entirely treasonous it worked perfectly.

I'm not suggesting Callaghan was a plant or that Wilson was a perfect shining example of the British Left.

But Wilson was the last PM who could seriously be considered even slightly on the Left, if only because he had more than a token reluctant interest in running the economy in a way that distributed wealth rather than concentrating it.

Since then power has been shared between the far-right and the centre-right, both of whom have been happy to continue with tax cuts, deregulation, privatisation, and wealth concentration.

As I said above, there has been no democractic choice about this, and no formal or organised democratic opposition to it.

I suppose you could argue that this reflects what the public wants. But I don't think the public is really all that enthusiastic about cuts in health care, affordable housing, or public transport. And the only reason it hasn't given oppressive white collar working practices a firm thumbs down is because there's an endless drumbeat of pro-market 'the economy needs...' which has made alternatives unthinkable.
