Sources at the very highest level are blaming a Treasury leak for freezing out the inhabitants of the Whitehall base of the Wales Office.
We’re talking literally here. The heating system at Whitehall is, apparently, interlinked and a leak at the Treasury has caused the boiler in Gwydyr House to malfunction just as temperatures plummet.
Incidentally, the same conversation also revealed that the heating at Gwydyr House is controlled by a thermostat at the Ministry of Defence.
It means if the Wales Office is feeling the heat or the cold, officials there have to ask MoD offficials to turn it up or down.

Please tell me that this is a new December Fool tradition being started. The boilers in Cardiff are controlled from Westminster? Are they included in Schedule 4?
No, it’s the Wales Office in London that’s part of the Whitehall heating system.
