A top executive at NSW’s Family and Community Services department has been a director of a company which donated to the Liberal party and sought a casino licence, business ventures an expert says conflict with his public service duties. Public servant Jim Longley is at the centre of a widening charity payments scandal under investigation by NSW Fair Trading. Mr Longley is chief executive of the $3 billion Ageing, Disability and Home Care division and also deputy secretary of the department of Family and Community Services.
