The Public Accounts Committee (PAC) has criticised HMRC for collecting £1bn less from the UK's "super rich" - individuals worth more than £20m - than it did in 2009.
While the PAC singles out the soccer industry as of particular concern it says that, although around one-third of individuals in the £20m-plus group was under enquiry at any one time, HMRC was not actively pursuing them for outstanding tax estimated as around £1.9bn in 2015-16 alone.
HMRC strongly defends itself against this allegation, but the PAC report is sure to reinvigorate the public debate on the tax affairs of the very rich. It will be interesting to see where HMRC goes now to in dealing with the tax affairs of the UK's super-wealthy.
The taxman's failure to get tough with the super-rich risks undermining confidence in the whole system, MPs warned in a report on Friday. HM Revenue and Customs must avoid the impression it has "one rule for the rich and another for everyone else," the Public Accounts Committee said.
