Leaving the EU: Parliamentary Vote

I share my hon. Friend’s concern about referenda. However, our result was not like the Republic of Ireland’s recent referendum result of 66:33, or whatever the maths is, and the difference was so fine. Does he not accept that, although I am not a great fan of referenda, and given that Mr Cameron has led us this far, a referendum is perhaps the only thing that could give either a stamp of approval or overturn things? I do not put any value judgment on either position. I am talking about giving clarity.
