I was going to quote David Cameron because I was asked for the words of a Conservative. On 10 November 2015, after announcing the referendum, he said:
“It will be your decision … Nobody else’s. Not politicians’. Not Parliament’s. Not lobby groups’. Not mine. Just you. You, the British people, will decide … And it will be the final decision. So to those who suggest that a decision in the referendum to leave … would merely produce another stronger renegotiation and then a second referendum in which Britain would stay … I say think again … There will not be another renegotiation and another referendum … Think very carefully, because this choice cannot be undone”.
