Norwood chairman Neville Kahn has resigned from his role as partner with insolvency practitioners Deloitte while facing an investigation into his conduct.
Mr Kahn is one of three Deloitte partners under investigation by the Institute of Chartered Accountants in England and Wales (ICAEW) over the administration of electrical retail giant Comet.
The collapse of the chain in 2012 cost the taxpayer £45 million.
The 55-year-old Hampstead Garden Synagogue member succeeded David Ereira in March as chair of Norwood, Britain's largest Jewish charity that works with vulnerable children.
