Video: David Cameron seeks to steady the ship in conference speech In his speech, which will mark the end of the Conservatives" four-day annual conference in Birmingham, Mr Cameron will "level with the British public" about the difficulty of the challenges facing the nation. He will say: "Unless we act, unless we take difficult, painful decisions, unless we show determination and imagination, Britain may not be in the future what it has been in the past. The truth is this, we are in a global race today and that means an hour of reckoning for countries like ours. Sink or swim, do or decline. The Conservative leader will say that there is "nothing complicated about me" and that it is his father's values of working hard, putting family first and putting back into the community that drive his political philosophy.
