《宋史·列传·卷一百一十九》
赵鼎说 ：萧振的本意不在大中。 萧振也对人说： 赵丞相不待指责，就会自行去位。 正好殿中侍御史张戒指责给事中勾涛，勾涛说： 张戒攻击我，是赵鼎的意思。 于是诋毁赵鼎结交台谏官员及诸将。
鼎曰： 振意不在大中也。 振亦谓人曰： 赵丞相不待论，当自为去就。 会殿中侍御史张戒论给事中勾涛，涛言： 戒之击臣，乃赵鼎意。 因诋鼎结台谏及诸将。
Zhao Ding said, "Xiao Zhen's goal was not Dazhong." Xiao Zhen also told people, "Chancellor Zhao will take the initiative to resign without waiting for criticism." It just so happened that Imperial Attendant Inspector Zhang Jie criticized Attendant Officer Gou Tao, and Gou Tao said, "Zhang Jie attacked me because of Zhao Ding's intention." He then accused Zhao Ding of associating with court officials and generals.
