contents We present a simple derivation of MHV amplitudes in massless spinor and scalar electrodynamics. Working with permutationally invariant amplitudes, we show that they are fully determined by their soft photon behavior and admit a simple factorized form in terms of soft factors and lower-point amplitudes. We prove these formulae using recursion relations. Finally, we consider possible extensions of these results by looking at supersymmetric theories, amplitudes beyond the MHV sector, gravity, and theories with charged particles of higher spins.
