We show that the theory of gravity constructed from the non-linear realisation of the semi-direct product of the Kac-Moody algebra A_{1}^{+++} with its vector representation does not allow a cosmological constant. The existence of a cosmological constant in this theory is related to the breaking of the gravitational duality symmetry.
