By Tom Bergin LONDON (Reuters) – Amazons tax affairs could come under more scrutiny in Britain, tax experts said, after a judge questioned whether it really was organized in the tax efficient way it said it was. The ruling comes as big technology groups, including Amazon, face increasing scrutiny in Britain over their tax practices. A UK judge ruled earlier this month that Amazon had infringed the trademark of soap maker Lush by posting advertisements on Google mentioning Lush soap and by offering customers who searched for Lush soap on its own website a list of options. Since Lush products were not available on Amazons UK website – on the manufacturers insistence – the judge ruled customers could be confused.
