Labour's Emily Thornberry has used a speech at a Holocaust Memorial Day commemoration to praise Jeremy Corbyn for "always calling out those people who play the race card".
Speaking during an emotional event at Islington Assembly Hall, the shadow foreign secretary praised presentations by local school children on the lessons that needed to be learned 75 years after the liberation of the Auschwitz death camp.
With Mr Corbyn also present, Ms Thornberry said it was not just the pupils who needed to carry on learning the lessons of history but "adults, especially the politicians amongst us".
Insisting that Islington had remained largely unified "with a bit of tension here and there," she added "Jeremy will always call out" those who play the "race card".
Ms Thornberry - who is an outside contender to replace Mr Corbyn as Labour leader in April - continued: "And I will too."
In his own speech, the Labour leader spoke of the need to recognise how "the Nazi Party rose to power and how the murdered six million Jewish people along with all the travellers and gypsies they could, along with lesbian and gay people."
Shoah survivor Hana Kleiner addressed the two-hour ceremony.
After detailing the mass murder of most of her family, Mrs Kleiner spoke of being depressed by "the current rise of antisemitism" and of Holocaust denial "in the face of all the documented evidence".
Pointedly the Czech-born survivor praised the Britain "for its traditions, for its tolerance and democratic lawful institutions which have been an example to others."
The ceremony also included an emotional speech from Bosnian survivor Mevilda Lazibi.
Earlier, Islington Mayor Councillor Rakhia Ismail gave a speech saying there was a "need to hold politicians to account" over genocides around the world.
But she suggested it was "Number 10 (Downing Street) and America or other parts of the world" who were guilty of "supporting blindly" these modern day atrocities.
Dame Margaret Hodge, a frequent critic of the party's response to antisemitism, told the Daily Telegraph: "If it wasn’t so serious, this would be a joke. I think Emily Thornberry needs to reflect on the reality before she makes statements like that."
Meanwhile Ian Austin, a former Labour MP who quit the party over Mr Corbyn's leadership to sit as an independent, said: "It’s easy to speak about racism at a Holocaust commemoration.
“But their words would have much more weight if the Labour Party had not been poisoned by racism against Jewish people under Jeremy Corbyn’s leadership.
"He could start to make amends by booting out the racists and apologising for his responsibility for this scandal before he stands down."
