The leaflets also accuse NHS managers of bullying and victimising staff who “express solidarity with Palestine or support the nurses and doctors killed or tortured by the Israeli military in Gaza”.

Ms Turner added: “These leaflets seek to undermine efforts to tackle anti-Semitism in the NHS, portraying anti-Semitism training as ‘pro-Israel indoctrination’ and dismissing the internationally recognised IHRA definition of anti-Semitism.

“It is particularly offensive to describe measures to protect Jewish healthcare workers and patients from discrimination as ‘racist’, while encouraging political demonstrations within healthcare settings.”

She added: “Jewish patients and NHS staff are entitled to feel safe and respected, without being confronted by hostile political campaigning. The Royal Free Hospital should investigate how these inflammatory leaflets came to be distributed on its premises and take steps to prevent its facilities from being used to promote such divisive messaging.”

Responding to the distribution of leaflets at Royal Free Hospital, Lord Mann told The Telegraph: “The NHS isn’t a place for people’s extremist politicking and the public is entitled, as are all staff, to use the NHS without any hostility.

“This should not be happening. People seeing this kind of thing won’t want to use the NHS, and we can’t have a bar on Jewish people, or anyone else, using the NHS. The country won’t have it.”

Security staff at the hospital saw activists distributing leaflets and asked them to leave, before gathering and destroying a number of the leaflets.

Activists have also handed out similar leaflets at University College Hospital, in central London.

The leaflets, under the headline Hands Off Our Health Workers, proclaim opposition to the Government’s plans to implement recommendations from a review into anti-Semitism in the NHS.

They claim the plans will result in a ban on Palestinian symbols in healthcare settings, will prevent criticism of Israel and introduce what they describe as “pro-Israel indoctrination” through staff training.
