UK Parliament · Commons Division 424 · 25 June 2019
247 Aye / 209 No · majority 38 · 4 tellers (not counted) · 1 both
Totals are Parliament’s official count, which does not include the tellers. Parliament’s published list names 245 of the 247 Aye voters and 208 of the 209 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.
