Troubled new political party Change UK has adopted the IHRA definition of antisemitism, saying the rise in Jew-hate "makes it incumbent on politicians of all persuasions to be unequivocal and uncompromising in our opposition to it".

The party has been reduced to five MPs after six of the founders - including Luciana Berger - left within weeks of the party being set up in February after disappointing results in May's European Parliament elections.

Ms Berger quit Labour that month over the antisemitic bullying she had faced since the party came under Jeremy Corbyn's leadership.

The party was engulfed in a huge row with the Jewish community last summer over the IHRA definition, which it initially refused to adopt in full because of examples it gave of how criticising Israel can be antisemitic.

On Thursday, Change UK leader Anna Soubry announced the party was adopting it in full.

She said: “Change UK and all our MPs stand in absolute opposition to antisemitism - in our values, our policies, and our practices.

“The resurgence in recent years of antisemitism within certain sections of British politics makes it incumbent on politicians of all persuasions to be unequivocal and uncompromising in our opposition to it.

“It is toward that end that without a moment’s hesitation, Change UK today proudly commits to adopting the IHRA definition of antisemitism in full, with all its examples.”

Board of Deputies President Marie van der Zyl said: “With antisemitism in the UK at record levels, it is incumbent on political parties to show that they take it seriously.

“Adopting the IHRA Definition of Antisemitism is a crucial step in that, and we welcome the fact that Change UK have adopted the Definition in full.”
