TAX avoidance campaigners have won High Court permission to challenge an alleged "sweetheart" deal between Goldman Sachs and HM Revenue and Customs (HMRC).

UK Uncut Legal Action was given leave by Mr Justice Simon, sitting in London, to seek a declaration that an agreement allowing the banking giant to skip a multimillion-pound interest bill on unpaid tax on bonuses was unlawful.

It wants £20 million allegedly involved to be returned to the public purse.

The judge ruled UK Uncut had "an arguable case" that should go to a full judicial review hearing.
