General Motors' chief executive Mary Barra is due to testify before the US Congress about the company's actions on faulty ignition switches.

Her appearance on Capitol Hill comes as GM recalled another 1.3m vehicles due to an electronic power steering threat which "could increase the risk of a crash", the company says.
