256 Aye / 287 No · lost by 31 · 4 tellers (not counted) · 1 both
Totals are Parliament’s official count, which does not include the tellers. Parliament’s published list names 254 of the 256 Aye voters and 286 of the 287 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.
