Lord Macmillan was replaced as Minister by Sir John Reith on 5 January 1940. Reith sought to improve the MOI's governance, expanded its network of Regional Information Offices and introduced a Home intelligence division. He also sought to secure the reintegration of the Press and Censorship Division in the belief that the decision to separate this function had been "obviously and monstrously ridiculous and wrong". These changes were announced by Neville Chamberlain on 24 April 1940 but were not fully operational until June 1940.
