Conservative Party chairman Grant Shapps has called on Liberal Democrat MP David Ward to withdraw remarks made over the Israel-Gaza conflict, which Labour said was a "vile" comment by a "desperate" MP.
"Appalling: No MP should Tweet what's essentially incitement to violence," Mr Shapps said. "Mr Ward must withdraw now. Completely irresponsible."
