Leading figures in the UK Jewish community are using Holocaust Memorial Day on 27 January to focus on the persecution of Uighur Muslims, saying Jews have the “moral authority and moral duty” to speak out.

Rabbis, community leaders and Holocaust survivors have been at the forefront of efforts to put pressure on the UK government to take a stronger stance over China’s brutal treatment of the Uighurs.

In a recent letter to the prime minister, Marie van der Zyl, president of the Board of Deputies of British Jews, said: “As a community, we are always extremely hesitant to consider comparisons with the Holocaust.”

However, there were similarities between what is reported to be happening in China and what happened in Nazi Germany in the 1930s and 40s, she said. Urging Boris Johnson to take action, she said violations of the Uighurs’ human rights were “shaping up to be the most serious outrage of our time”.
