The Chief Whip of U.K.'s Labour party, Rosie Winterton, will speak to Sir Gerald Kaufman, a veteran British parliamentarian who caused a storm last week by saying that the ruling Conservative Party is influenced by “Jewish money" and that the Israeli government made up the recent spate of violent attacks in order to allow it to “execute Palestinians."

The Labour party was called to action by a letter from the Board of Deputies, Community Security Trust (CST) and Jewish Leadership Council, demanding they take "swift and appropriate disciplinary action," the Jewish Cronicle reported.

Kaufman, a long-time Labor member of parliament, was speaking at an event in Parliament hosted by the Palestine Return Centre, a group that is reportedly aligned with Hamas. His comments were recorded by blogger David Collier and published in the Jewish Chronicle.

Four of Britain’s most prominent Jewish organizations – the Board of Deputies, the Campaign Against Antisemitism, the Jewish Leadership Council and the Community Security Trust – expressed Thursday their outrage at Kaufman's comments and demanded that they be investigated, The Spectator reported.

“It’s Jewish money, Jewish donations to the Conservative Party – as in the general election in May – support from the Jewish Chronicle, all of those things, bias the Conservatives," Kaufman said.

“There is now a big group of Conservative members of parliament who are pro-Israel whatever government does and they are not interested in what Israel the Israeli government does."

Kaufman, the longest-serving parliamentarian in Britain (known as Father of the House of Commons,) also criticized Conservative MPs for ignoring the ongoing violence in Israel.

"In the last few days alone the Israelis have murdered 52 Palestinians and nobody pays attention and this government doesn’t care,” he said.

He then told the audience of about 45 people that the Israeli government had made up the recent spate of violent attacks in order to allow it to “execute Palestinians”. His source for that statement was “a friend of mine who lives in East Jerusalem,” the Manchester MP said.

Kaufman has not responded to requests to comment on the remarks. A spokesman for the Palestine Return Centre distanced the group from the comments but refused to rule out inviting him to speak at future events.

“The views as reported do not reflect the views of the party," a Labor Party spokesman said. He would not comment on whether the party would reprimand Kaufman or ask him to resign.

Kaufman caused controversy earlier this year when he said that Israel uses the Holocaust to justify murdering Palestinians. He is infamous for saying, "Here we are, the Jews again," when fellow Labor MP Louise Ellman rose to speak in parliament in 2011.
