Fourteen-day rule

From dKosopedia

The fourteen day rule was an informal norm adopted during the Second World War whereby the BBC would not broadcast discussion of issues on radio and television for two weeks that had come before either the House of Commons or the House of Lords. The British public was given two weeks to make up its own mind before hearing from broadcast pundits. The norm was abandoned in 1955.
