Rosie Chapman, the director of policy and effectiveness at the Charity Commission, has taken voluntary redundancy and will leave the organisation in May.
Chapman, who has worked at the commission for 10 years, is the most senior of 57 staff who have so far accepted the voluntary redundancy package offered by the commission to all its employees in January.
Chapman will receive a month’s pay for each year she has worked at the commission. The regulator’s accounts show she was paid between £85,000 and £90,000 in 2009/10, the most recent year for which figures are available.
Chapman told Third Sector she did not have another job lined up, but would look for roles in the voluntary sector.
"Leaving on voluntary terms allows me to do what I want, and there’s no point in scurrying around looking for a new role without thinking about what I want to do," she said. "I’m tempted to work for a charity, whether it’s paid or as a trustee."
She said she had decided to leave because "it was time for a change" after a decade at the commission.
Asked whether she thought cuts to the commission’s budget of more than a quarter, from £29.3m in 2010/11 to £21.3m in 2014/15, would damage the regulator, she said: "I have every confidence that the strategic review will point the commission in the right direction.
"It will be a different organisation, but what works in one season might not work in another," she said.
