Lord Hague, a former Tory leader, loudly denounced Tony Blair, a former Labour prime minister, for inviting people to “rise up” against Brexit (see Bagehot). Lord Mandelson, Mr Blair’s close ally, responded that Brexit supporters did not want Britain to be poorer and politically isolated, and so should be entitled to change their minds. Lords Lawson and Lamont, both former Tory chancellors, attacked as undemocratic the idea of amending a bill that had not only passed the Commons unscathed but also reflected one of the biggest votes in British history.
前保守党领导人黑格强烈谴责前英国首相布莱尔怂恿民众“起义”反对脱欧(详见巴杰特)。布莱尔的亲信曼德尔森回应说,脱欧支持者不希望英国出现国力衰退,政治上被孤立的情况,当然他们也有权利改变他们的主意。前保守党大臣劳森和拉蒙特将此修改条款的做法视为非民主的行为,这不仅能毫发无损地通过下议院颁布这项法令,也反映了英国史上影响力范围最大的一次投票。
