Damn foreigners, coming over here taking our power companies, when all we get is the school buses in the USA (owned by a subsidiary of Stagecoach) and a defective offshore oil well there (owned by...oh, never mind).
Bit late to be complaining about multinational companies or what arrangements are made by EU states over corporation tax. . What's the French for 'swings and roundabouts' ?
It rather looks as though the bulk of EDF's profit growth was outside the UK. It's strong in nuclear energy, referred to in the original link, which France uses a lot more than we do, and that interest has contributed.
But, that said, big companies will always charge what they can get away with.
