Business Diary: Singing the same tune at last

Anyone who thinks trade union leaders are too busy reading Marx to have a sense of humour should have been at the Unite meeting of British Airways cabin crew held following yesterday's agreement with the airline. Unite leader Len McCluskey told members he was exhausted following the lengthy dispute but still on his feet. Then he played Elton John's I'm Still Standing to emphasise the point.

Round Two. Two years ago, Rolling Stone magazine's Matt Taibbi scored a direct hit with his description of Goldman Sachs as a "giant vampire squid". Now Taibbi is back with a new piece on the investment bank – and if anything, it's even less flattering.

Unreconstructed dinosaurs can use the figures to cement their prejudices; more modern thinkers will note the insurance company reckons most of the difference is down to the fact that women, on average, earn 41 per cent less than men.
