Hansard (Pre) Referendum Debate Wednesday 15 June 2016
Nigel Adams
(Selby and Ainsty) (Con)
Q14. I congratulate my right hon. Friend on honouring our manifesto pledge and delivering this historic referendum. Unfortunately, however, we have heard some hysterical scaremongering during the debate, and there are those in this House and the other place who believe that if the British people decide to leave the EU, there should be a second referendum. Will he assure the House and the country that, whatever the result on 24 June, his Government will carry out the wishes of the British people—if the vote is to remain, we remain, but if it is to leave, which I hope it is, we leave?
The Prime Minister [David Cameron]
I am very happy to agree with my hon. Friend. “In” means we remain in a reformed EU; “out” means we come out. As the leave campaigners and others have said, “out” means out of the EU, out of the European single market, out of the Council of Ministers—out of all those things...
