HMRC tax deal with Vodafone 'may have been illegal' 

A highly controversial tax deal which cost the public purse billions may have been illegal, according to allegations being examined by a powerful parliamentary committee.

The public accounts committee is considering claims from a whistleblower who says that an agreement to waive a potential tax bill of up to £7bn from Vodafone may have been outside the powers of HM Revenue and Customs (HMRC).
