Baroness Warsi has claimed that she was ostracised by the Jewish community after she resigned from her government post over the UK’s policy on the Gaza conflict.

She said Jews who were once friends no longer spoke to her.

But Laura Marks, the senior vice president of the Board of Deputies, who was pictured embracing Baroness Warsi at interfaith events, denied the claim.

Baroness Warsi resigned as Minister for Faith and Communities in the summer, claiming that the government’s failure to condemn Israel over Gaza was “morally indefensible”.

Today, in a series of tweets, some directly to the Board of Deputies, and another directly to Ms Marks, she wrote: “People whom I considered friends from the British Jewish community stopped all communication with me after my resignation.

“I was shocked at the vitriolic abuse I got for resigning from people self-identifying as British Jews.”

She added: “I hope that in 2015 my friends in the British Jewish community can judge me on my 20 years of fighting antisemitism and interfaith work and not just on my principled resignation. We all have a duty to defend human rights, the rule of law and international justice.”

But Ms Marks, who once led Jewish and Muslim women interfaith initiatives with Baroness Warsi, said she “tried to reach out to her after she resigned, but I found it very hard.

“I tried her office, her phone, she never replied. Despite trying to reach out, I couldn’t get through.

“I understand she’s saying the Jewish community has cut her off – but personally, and from the Board, that’s not the intention at all.”

Ms Marks said she had not been able to speak to Baroness Warsi since she resigned but hoped they could rebuild their relationship.

She added: “We as British Jews have to build relationships.

“Baroness Warsi was the greatest supporter of interfaith relationships, a great friend of dialogue. She resigned over Gaza – not interfaith – but it just shows how the two are related to one another.

"It demonstrates how delicate these interfaith relationships are and the importance of treating each other with respect and care."

Baroness Warsi later responded to Ms Marks, tweeting: “Pleased to learn today that Laura Marks tried to reach out to me post my resignation. Tea in the new year?”
