A Whitehall mandarin who faced intense criticism from MPs while holding key Civil Service roles is quitting, the Government has announced.
Lin Homer will stand down as HM Revenue and Customs chief executive in April after four years in the role, the department said.
Ms Homer, who was made a Dame in the New Year's Honours list, came under fire last year for her handling of tax-dodgers.
Chancellor George Osborne said: "Lin Homer has made a real contribution to public service modernisation and transformation. She has put the foundations in place that will see HMRC become one of the most digitally-advanced tax authorities in the world.
"It is to Lin's great credit that the National Audit Office last year judged HMRC to be one of the strongest Departments in Government - a legacy of which she can be rightly proud."
