The reason is that the electoral system that votes Members to this House is a matter on which there is profound disagreement between the parties, whereas the principle of House of Lords reform is something to which we have committed ourselves in all our party manifestos over a prolonged period.
It is essential that we make a start by having the first 120 elected peers elected in 2015. If the hon. Gentleman or other Members of this place want further reassurance about the triggers that would then allow the second and third waves of election to take place, of course I, and the Government as a whole, will be prepared to engage with that.
