Bill Mc Lennan - Central Statistical Office, United Kingdom

Central Statistical Office, United Kingdom

In 1992, McLennan was appointed Director of the Central Statistical Office (CSO) and head of the Government Statistical Services of the United Kingdom. He was the first person from outside the UK to be appointed to that post.

During his tenure, he proposed the merger of the OPCS and the CSO in August 1994, which was subsequently announced by Prime Minister John Major in September 1995 following a consultation period and took place on 1 April 1996 when the Office for National Statistics was launched. He persuaded the Chancellor of the Exchequer, Norman Lamont, to reduce ministerial access to economic statistics in advance of publication and to permit statistics to be released independently of ministers. He produced the Official Statistics Code of Practice, first published in April 1995, which set good practice and principles for statisticians producing official statistics with the aim of promoting high standards and maintaining public confidence in official statistics. He led the CSO through its early years as a 'Next Steps Agency' with demanding and quantified targets for the accuracy of statistics.
