We will discuss the origin of the conjectured colour-kinematics
duality in perturbative gauge theory, according to which there is a
symmetry between the colour dependence and the kinematic dependence of the
S-matrix. Based on this duality, there is a prescription to obtain gravity
amplitudes as the "double copy" of gauge theory amplitudes. We will first
consider tree-level amplitudes, where a diffeomorphism algebra underlies
the structure of MHV amplitudes, mirroring the colour algebra. We will
then draw on the progress at tree-level to consider one-loop amplitudes.
