285 Aye / 7 No · majority 278 · 4 tellers (not counted) · 3 both
Totals are Parliament’s official count, which does not include the tellers. Parliament’s published list names 282 of the 285 Aye voters and 4 of the 7 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.
