//Cynical key set to 11:
The Palace of Westminster needs a huge overhaul, and there has long been talk of closing one chamber at a time, and moving one house or another elsewhere whilst the refit is in progress.
Cue moving the HoL to York (other cites are available) so that the Commons can simply move down the corridor whilst their house has the builders in. Once that is done builders and Commons swop over.
In around a decade both houses will have been refurbished. Cue PM of the day declaring that having a second house so far away is financially unsustainable. So sorry northern people, sure you understand, look at all the legacy builds we are leaving behind.
HoL moves back to Westminster.
Political wins in both decades.
Cynical key to normal.//
