Probably because some Labour MPs have left due to antisemetism, and many high-profile members are on the receiving end.

Antisemetism is a popular view in the west, and globally.

Actually the introduction of the article was about a little more than that. More like a « history of anti-semitism in england ». Which resonates for anyone that has been following the recent stories about current’s labour party indeed.

The Labour party have been embroiled in anti semitism controversy for the last few years.

It largely stems from their leader's former links to Hamas and Palestinian movements, and then the party's cack-handed response to the controversy.

Eg. Being very slow to discipline known antisemites within the party, watering down the Working Definition of Antisemitism, senior figures being members of Facebook groups containing antisemtic content, etc.
