He had been responsible for tightening the PCC's Code of Practice in the wake of the death in 1997 of Princess Diana. The Lord Black proposals frequently referred to throughout the Inquiry were his proposals for a new system of independent press self-regulation and were put forward on behalf of the newspaper industry.
