Sarah Atkinson’s new head of corporate affairs position replaces the head of comms role held by Antony Robbins for the past four years.
Atkinson has been brought on board to give the commission a greater clout in policy-making circles.
She said her first challenge was working on the ‘crucial’ Charities Bill that had its second reading in Parliament this week.
Atkinson’s appointment comes as the commission confirms that Dame Suzi Leather will be its next chair.
Leather will take over from current chair, Geraldine Peacock CBE, on 1 August.
Robbins has left to join the Department for International Development as a policy adviser specialising in water projects in the developing world.
