UK Parliament · Commons Division 421 · 19 June 2019
211 Aye / 132 No · majority 79 · 4 tellers (not counted) · 1 both
Totals are Parliament’s official count, which does not include the tellers. Parliament’s published list names 210 of the 211 Aye voters and 131 of the 132 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.
