      李祥,字元德,常州无锡人。隆兴元年进士,为钱塘县主簿。时姚宪尹临安,俾摄录参。逻者以巧发为能,每事下有司,必监视锻炼,囚服乃已。尝诬告一武臣子谤朝政,鞫于狱,祥不使逻者入门。既而所告无实,具以白尹,尹惊曰:“上命无实乎?”祥曰:“即坐谴,自甘。”宪具论如祥意,上骇曰:“朕几误矣,卿吾争臣也。”遂赐宪出身为谏大夫,祥调濠州录事参军。安丰守臣冒占民田,讼屡改而不决,监司委祥,卒归之民。未几,其人易守濠,以嫌换司理庐州;守出改官奏留之,不可。主管户部架阁文字、太学博士、国子博士、司农寺丞、枢密院编修官兼刑部郎官、、大宗正丞、军器少监。言:“忝朝迹八年,在外贤才不胜众,愿更出送入由臣始。”出提举淮东常平茶盐、淮西运判。两淮铁钱比不定,祥疏乞官赐钱米销滥恶者,废定城、兴国、汉阳监,更铸绍熙新钱,从之,淮人以安。迁国子司业、宗正少卿、国子祭酒。

       韩侂胄恃功,为丞相赵汝愚所抑,日夜谋引其党为台谏,以摈汝愚。汝愚为人疏,不虞其奸。侂胄逐汝愚而难其名,擢其党将作监李沐为正言。沐奏:“汝愚以同姓居相位,将不利于社稷,乞罢其政。”汝愚出浙江亭待罪,遂罢右相。汝愚以言去国祥上疏争之曰顷寿皇崩两宫隔绝中外汹汹留正弃印亡去国命如发。汝愚不畏灭族,决策立陛下,风尘不摇,天下复安,社稷之臣也。奈何无念功至意,忽体貌常典,使精忠巨节怫郁黯暗,何以示后世?”除直龙图阁、湖南运副,言者劾罢之。于是太学诸生杨宏中、周端朝等六人上书留之,俱得罪。主冲佑观,再请老,以直龙图阁致仕。嘉泰元年八月卒,谥肃简。
