A relevant quote about Churchill. General Sir Alan Brooke, Churchill's chief of staff, wrote that "Winston had 10 ideas every day, only one of which was good, and he did not know which it was".

And from the Churchill Centre Churchill's mistakes

Another thing that bugged me about the Churchill family was the sale of the 'Churchill Papers' a few years ago. These were papers dating from Winston's time as Prime Minister. Many people regarded them as 'stuff he nicked from work'! How come they didn't belong to the nation anyway?
