§ Mr. Griffithsasked the Lord President of the Council if he is aware that the telephone numbers for the private offices of Ministers, as printed in the last edition of the Palace of Westminster telephone directory, are frequently wrong: why some of those numbers, notably those with the prefix 224 as in the case of Ministers at the Department of Health and Social Security, are not yet in operation though listed nearly six months ago: and if, for the convenience of hon. Members and the parliamentary switchboard, he will take steps to ensure that the directory is corrected.
