Video: David Cameron: Scotland is better off in Britain Mr Cameron used his speech to the Scottish Conservative conference in Troon, Ayrshire to pledge that the party would "fight with everything we've got" to keep the United Kingdom together as he told Scotland's First Minister to "stop dithering and start delivering" on the referendum. The Prime Minister claimed the union between the countries had made Britain "one of the world's greatest economic and political success stories." On the subject of the referendum, he was clear that Scots should get a "clear choice" in the ballot: "Yes or No, in or out of the United Kingdom." He continued: "Delay creates uncertainty for businesses, investors, families. People need to know one way or the other. So my message to the First Minister is this: stop dithering and start delivering. Let's give the Scottish people the chance to make a clear choice about their future.
