Tax dodging and non-compliance during the pandemic cost the Government £9billion, Whitehall's spending watchdog has found.
Thousands of staff who usually checked people and businesses were paying the right amount of tax were moved to Covid support schemes by HM Revenue & Customs (HMRC).
Around 1,350 workers were redeployed to Covid schemes throughout 2020-2021, shrinking the number of those working on tax compliance by 12%, according to the National Audit Office (NAO).
