We introduce a new method for reconstructing the primordial power spectrum, P (k), directly from observations of the Cosmic Microwave Background (CMB). We employ Singular Value Decomposition (SVD) to invert the radiation perturbation transfer function. The degeneracy of the multipole to wavenumber k linear mapping is thus reduced. This enables the inversion to be carried out at each point along a Monte Carlo Markov Chain (MCMC) exploration of the combined P (k) and cosmological parameter space. We present best--fit P (k) obtained with this method along with other cosmological parameters.
