------------------------------------------------------------------------ `The E6SSM' Abstract: I will discuss the Exceptional Supersymmetric Standard Model (E6SSM), which is a gauge theory inspired by GUT unification under the group E6. Although the model itself does not exhibit an E6, nor describe how GUT scale E6 breaking would occur, it includes the particle content consisting of one 27-plet of E6 per generation. I will describe the low energy particle spectrum, as derived from the renormalisation group running, and discuss the low energy collider phenomenology. I will also point out some cosmological consequences, such as dark matter and lepto-/baryogenesis. ------------------------------------------------------------------------
