3. SOUNDBITE (English) David Cameron, former British Prime Minister:
"I, you know, thought throughout the referendum campaign, I always knew there was a danger that my side would lose and the other side would win, and I suppose I could have fought the referendum as the prime minister saying 'well, it's a big decision for the country, you decide' on the one hand. On the other hand, and stood back from it, but that's not what I'm like. I was passionate about my side of the argument, I threw myself into the argument, I made every argument I could, I fought as hard as I could. But I knew that if I lost, I would have to think about resigning."

7. SOUNDBITE (English) David Cameron, former British Prime Minister:
"I would argue that while it was a difficult decision to resign. Actually I think you can see in the new Prime Minister Theresa May someone who believes very much in what they are doing, is doing an excellent job, is taking the country forward and I think will deliver what's required, which is to be out of the European Union but working very closely with our friends and our allies, France and Germany and Italy and all the countries of the European Union, and also staying with our friends including here in the Ukraine. So a difficult decision but the right one because credibility and passion are what you need in politics and I realised, having lost the referendum, the right thing to do was to allow someone else to come forward and take Great Britain forward."
Former British Prime Minister David Cameron said on Wednesday that he "fought as hard as I could" for the argument that Britain should remain in the European Union.
Speaking as a guest of honour at the Viktor Pinchuk Foundation in Kiev, Cameron added he knew that if he lost the argument for the United Kingdom to remain as part of the bloc, "I would have to think about resigning."
Cameron confirmed in his general election victory speech in 2015 that there would be an in/out referendum on European Union membership.
He said on Wednesday he knew during the subsequent referendum campaign that "there was a danger that my side would lose."
Cameron said British Prime Minister Theresa May was doing an "excellent" job and was taking the UK forward.
