《宋史·列传·卷一百六十六》
阻遏台谏的话还可以，甚至把陛下的旨意藏起来不实行，这难道是励精新政时所应该有的吗？ 丞相郑清之见到这个奏章后大怒，五次上疏请求免去杜范的官职，他的奏疏中有 危机将要发生，朋党祸起 的话；并且认为杜范秉承某人的微言示意，来装饰自己对大臣的排挤和陷害。
阻台谏之言犹可也，至于陛下之旨匿而不行，此岂励精亲政之时所宜有哉！ 丞相郑清之见之大怒，五上章丐去，有 危机将发，朋比祸作 之语；且谓范顺承风旨，粉饰挤陷。
It is acceptable to obstruct the remonstrating officials' words, and even hide the Emperor’s edict and not implement it. Is this what it should be when striving for a new government? After seeing this memorial, Prime Minister Zheng Qingzhi was furious and submitted five memorials requesting that Du Fan be relieved of his post. His memorials contained the words "Crisis is imminent, and party disasters are rising"; and he believed that Du Fan followed someone's hints to embellish his exclusion of and harm to ministers.
