Nuclear regulator under scrutiny for its directors' tax arrangements
In February 2012, Brown was one of two ONR senior officials who had their contracts terminated by the Health and Safety Executive after it emerged via the Exaro investigative website that they were receiving payment through private companies rather than the staff payroll. Brown was paid via his company Operations Improvements Ltd, based in Surrey.
Friends of Brown however claimed he was a legitimate freelancer working with a range of corporate clients. His company reported an income of more than £145,000 in the financial year 2011 according to the Guardian.
