Is the Prime Minister in a position to promise us an early issue of the white paper?
A document issued by the Government laying out its policy, or proposed policy, on a topic of current concern.Although a white paper may occasion consultation as to the details of new legislation, it does signify a clear intention on the part of a government to pass new law. This is a contrast with green papers, which are issued less frequently, are more open-ended and may merely propose a strategy to be implemented in the details of other legislation.
