Google will face a fresh grilling over its tax affairs after the global corporation was recalled to give evidence to a parliamentary inquiry.
Vice president Matt Brittin is due to appear before the Commons Public Accounts Committee just months after it last quizzed the firm about its low tax bill.
It comes as the chairwoman of the committee, Margaret Hodge, revealed that Amazon also faced being hauled back to explain its financial dealings after a Guardian investigation claimed its company filings showed its main UK company paid £3.2 million in corporation tax on sales of £320 million last year while the Seattle-based group told investors its 2012 UK sales were £4.2 billion.
Mrs Hodge told the Guardian: "My committee has real concerns about the extent to which companies like Amazon are stretching the rules in order to avoid paying their fair share in tax.
"By any measure of common sense Amazon appears to have a proper established presence in the UK, and that there is a discrepancy between some of the evidence in this report about its activities in the UK and what the committee was told by Amazon when they appeared before us last year. We will now consider whether we need to recall them to explain that discrepancy."
A report last December by the committee accused both companies, along with Starbucks, of ''immorally'' minimising their UK tax bills.
The firms were criticised for the ''unconvincing and, in some cases, evasive'' evidence they gave on why their corporation tax payments are so low.
