The National Government was concerned about the morale of the people during the dark days of 1940/41. The Prime Minister (Winston Churchill) delivered his famous inspirational speeches in Parliament (and sometimes to other prestigious gatherings) -- but they were really directed at the British people and the BBC and the Newspapers gave them the widest dissemination.
Local Government leaders exerted a lot of effort to boost the Morale of the public too. They published and distributed inspirational fliers and notices at Schools, Churches, Organizational Meetings, etc. and in the local newspapers.
