Tax avoidance
This game has always struck me as a tax avoidance scheme, now somebody has finally closed the loophole.
The problem being of course that the damage has already been done to the UK jobs market. Any company that's outsourced all these services offshore is going to have to work out which is cheaper, to bring it all back in house or to pay the VAT. I'll bet it would take a few years to break even. So existing jobs will probably stay offshore, only the new ones will be in house.
