Tory leader David Cameron, pictured, yesterday told the Conservative Party conference that a high speed canal link with Central America will be better for the country's economy than a third runway at Heathrow. "A man, a plan, a canal: Panama," he said to wild applause from the Tory faithful. Cameron went on to criticise Prime Minister Gordon Brown. "Go deliver a dare, vile dog," he said before putting the boot into the Lord Chancellor too. "Straw, no, too stupid a fad, I put soot on warts," said Cameron. The Conservative leader also addressed the question of his lack of experience. "Go hang a salami! I'm a lasagna hog!" he claimed angrily.
