412 Aye / 202 No · majority 210 · 4 tellers (not counted) · 1 both
Totals are Parliament’s official count, which does not include the tellers. Parliament’s published list names 412 of the 412 Aye voters and 201 of the 202 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.
