Ellman is rabidly anti-Hamas and rabidly pro-Israel. Anyone reading the two posts above should be aware of that.

She voted "very strongly for" the Iraq War, "very strongly against" an investigation into that war, and "very strongly for" renewal of Trident, Britain's nuclear weapons programme.

Ellman is also the Chair of the Jewish Labour Movement and Vice Chair of Labour Friends of Israel and has been an active spokeswoman in Parliament on issues relating to the Middle East. Ellman is a member of Labour Friends of Israel. [On the] assassination of Sheikh Yasin, the 66-year-old spiritual leader of Hamas, [she] told Parliament that "Israel's action in killing Sheikh Yasin was a legitimate response to an extraordinary situation". In January 2011, during a debate on Antisemitism she asked: "Does the hon. Gentleman share my concern that the anti-Semitism that he describes is rarely opposed by those who declare themselves anti-racist?"

In the 2010 Election campaign leaflets had been distributed in her constituency of Liverpool Riverside targeting Mrs Ellman and Luciana Berger for their membership of Labour Friends of Israel and was headed "Don't vote for Friends of Israel". A leaflet headed "Remember Gaza" and subheaded "Don't vote for Labour Friends of Israel" was written and widely distributed by Liverpool Friends of Palestine and appears on the website LabourNet. An article appeared in The Jewish Chronicle entitled "Racist leaflets against Jewish candidates in Liverpool."

Not a great "authority" then, Keith.
