Another important criticism of the report's recommendations is that adding some elected members to the House might create two 'classes' of members; the elected members might be seen as having greater democratic legitimacy and authority than the appointed members. This could also threaten the traditional primacy of the House of Commons within the Westminster parliamentary system. One commentator, the Liberal Democrat peer Lord McNally, wrote in January 2000: "Those who fear that a House of Lords with increased authority will challenge the status of the Commons and cause constitutional conflict - or "gridlock" as the Americans call it when the Senate and the House of Representatives disagree - will worry that the Wakeham proposals set us on just that course. On the other hand, those who believe that the second chamber must have the full democratic mandate which only the ballot box can bestow will be disappointed."
