Chief Economic Adviser to the Treasury, Clare Lombardelli, has
  been appointed as the new OECD Chief Economist – the first time a
  British person has held this role in thirty years.
  As OECD Chief Economist, Clare will be working with OECD member
  countries and partners to confront difficult macroeconomic and
  structural challenges. She will lead the OECD’s economic work,
  replacing France’s Laurence Boone, who has held the post since
  2018. 
  Clare has worked in government since 2005, after starting her
  career as an economist at the Bank of England. During this time
  her roles have included Principal Private Secretary to the
  Chancellor, Private Secretary for Economic Affairs to the Prime
  Minister and Budget Director. She has also worked as a technical
  adviser for the International Monetary Fund. She will step down
  from the Treasury after the Spring Budget.  
  Chancellor  said:
  “Clare is an exceptional civil servant – throughout her time in
  government she has always delivered clear and level-headed
  advice. Most recently she has led teams at the Treasury to
  promote sustainable economic growth and setting and implementing
  fiscal policy.
  “I congratulate Clare on her well-deserved appointment. It’s
  great to have a Brit in the role and look forward to working with
  her in the future.”
  Permanent Secretary to the Treasury  said:
  “I’m delighted Clare is being appointed to such a key
  international role. With her proven economic experience and
  leadership over almost 20 years in government, she fits the
  job very well.
  "Clare has been an exceptional Chief Economic Adviser and
  colleague at the Treasury making a huge contribution under
  successive Governments and I wish her all the best.”
  Clare Lombardelli said:
  “I look forward to taking up my new role, leading the OECD’s
  economic work to improve policies to benefit people around the
  world. I have loved my time in the civil service and the Treasury
  - it has been a huge privilege to work with such talented,
  dedicated and supportive colleagues as we’ve tackled the UK’s
  biggest economic challenges.”
  A recruitment process for Clare’s replacement will be set out
  shortly by the Treasury.
