The electromagnetic properties of a Fermi liquid superconductor with singular Landau parameter F1s→-1, corresponding to a state with marginal spin-charge separation (MSCS) is analyzed in this paper. We show that the MSCS state describes a strongly phase-disordered superconductor which is a diamagnetic metal with Drude-like optical conductivity. The phase diagram and electromagnetic properties of the MSCS state is found to be in qualitative agreement with what is observed in the pseudo-gap phase of (underdoped) High-Tc cuprates. We predicted that vortices with \em un-quantized magnetic flux will be observed in the pseudo-gap phase.
