European Union (Notification of Withdrawal) Bill

I am grateful to the hon. Gentleman for allowing me to intervene when he was about to get into full flow. He and his colleagues in the Democratic Unionist party know perfectly well that a clear majority of the Northern Ireland electorate voted for the UK to remain within the EU. A majority of my constituents in North Down voted to remain. How do he and his party colleagues propose to respect that fact in their voting tomorrow evening, and indeed in their negotiations with the Brexit Secretary?
