Google 'must be investigated over tax' - MPs

Google should be "fully investigated" by HM Revenue and Customs after information from whistleblowers "undermined" the firm's defence of its tax arrangements, a committee of MPs has said.

The tech firm says that advertising sales take place in low-tax Ireland, not the UK, but the Public Accounts Committee said it had been told by ex-employees of Google that UK-based staff are engaged in selling.

Google said it complies with all the tax rules in the UK.
