History. No count: the day each past vote was announced was not recorded.
Hunch. BBC reported on 5 and 7 November that government whips have discussed a debate and vote before the new year, and the last condition the minister named, the committee report, came out on 4 November.
The day market resolves YES if by the end of 17 December 2026 the Leader of the House, in a Thursday business statement in Hansard, or the Commons order paper names a specific sitting day for the repairs motion, including a day in 2027, a day later withdrawn, or a vote already held; words like 'in the new year' or 'shortly' are NO. BBC News and The Guardian settle it if Hansard is silent.
We looked for cases where a UK government promised the House of Commons a vote on how it runs itself, from MPs' conduct to its own building, without giving a date. We found seven such promises since 1995, two of them about these same repairs.
