Is Amazon UK a tax evader?

How do you generate £3.3bn of UK sales yet pay no corporation tax on any of the profits? Just ask Amazon. Amazon is the UK's biggest online retailer, responsible for 25% of all books sold in the UK. It is bigger (online) than Tesco.

Yet the ownership of the operation is based in Luxembourg - employing just 130-odd people - which is where most Amazon payments and profits go.
