In Britain, the tax affairs of 27 MPs are being investigated by HM Revenue and Customs department. HMRC said it would not reveal the identities of the M.Ps involved or elaborate on what is being looked into. The move follows a warning in July from HMRC head Dave Hartnett that M.Ps would be placed under extra scrutiny in revelations about expenses claims. A spokeswoman said inquiries are an integral part of HMRC's work ensuring that everyone pays the right tax. The Committee on Standards in Public Life, which is examining proposed future reforms to the expenses system, will publish its report on 4 November.
