Deep in the Westminster Vaults

*Surveys the meticulously painted runes required for a meso-scale trans-location, sigils that are now useless and beginning to smell due to the wards: newly strengthened by Bercow's return.*

*attempts to cast a cleaning charm*

*after sheltering from the haphazard whirlwind of soap-suds and bleach, decides to try cleaning it up manually*

Machine, I require tea.

...and also some sort of cleaning implement

*ponders*

*rearranges the runes in one corner to form a slightly smaller summoning circle*

*steps back and mouths a few words until what appears to be a very trim racing broom appears*

*smirks and begins to clean up the mess*
