Russia Today TV presenter Liz Wahl quits on air

For the second time American presenters on the Russian backed TV station Russia Today have gone off script to voice their personal concerns about Russia's occupation of the Crimea region of Ukraine.

On Tuesday, Abby Martin signed off her programme with an ad-libbed attack on the Kremlin. Now her colleague Liz Wahl has added her voice to the disquiet among the channel's on air staff by announcing her resignation on air.
