Boris Catapults Greens

Boris brought the house down during his first question time. He was asked by the Greens if he had considered their alternative plans for a new means of spanning the Thames. Crikey what's this? Boris beamed enthusiastically.  He then drew on his knowledge of the classics - Caesar propelling his troops across the Rubicon. "Do you envisage a kind of catapult?" he asked, to much merriment.
