In the Standard Model (SM) we calculate the decay rate of the neutron radiative ${\ensuremath{\beta}}^{\ensuremath{-}}$ decay to order $O({\ensuremath{\alpha}}^{2}/{\ensuremath{\pi}}^{2}\ensuremath{\sim}{10}^{\ensuremath{-}5})$, where $\ensuremath{\alpha}$ is the fine-structure constant, and radiative corrections to order $O(\ensuremath{\alpha}/\ensuremath{\pi}\ensuremath{\sim}{10}^{\ensuremath{-}3})$. The obtained results together with the recent analysis of the neutron radiative ${\ensuremath…
