UK Parliament · Commons Division 274 · 4 December 2018
321 Aye / 299 No · majority 22 · 4 tellers (not counted) · 1 both
A Business of the House motion governs how the Commons orders its time, including which days are given over to which sorts of debate. The government tables most of these; they pass routinely but are sometimes used to short-circuit opposition procedural objections.
Totals are Parliament’s official count, which does not include the tellers. Parliament’s published list names 320 of the 321 Aye voters and 298 of the 299 No voters; tellers are listed and marked but not counted.
Walking through both the Aye and No lobbies is a recorded form of deliberate abstention.
