245 Aye / 2 No · majority 243 · 4 tellers (not counted) · 2 both
Totals are Parliament’s official count, which does not include the tellers. Parliament’s published list names 243 of the 245 Aye voters and 0 of the 2 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.
