《宋史·列传·卷六十九》
起初，真宗身体不适，寇准议奏皇太子总管军国之事，李迪赞同此策，丁谓认为不妥，说： 等到以后陛下身体康复，朝廷又将怎样处理此事呢？ 李迪说 ：太子监督国事，难道不是古已有之的制度吗？ 
初，真宗不豫，寇准议皇太子总军国事，迪赞其策，丁谓以为不便，曰： 即日上体平，朝廷何以处此？ 迪曰： 太子监国，非古制邪？ 力争不已。
Initially, Zhenzong was indisposed, Kou Zhun proposed to the imperial court that the Crown Prince take charge of military and state affairs, Li Di was in agreement with this strategy, Ding Wei believed it was inappropriate, and said: When His Majesty's health improves in the future, how will the imperial court handle this matter? Li Di said: The Crown Prince supervising state affairs, isn't that an established practice from ancient times?
