New today/this week

The immediate surge in antisemitism incidents following the Manchester attack is unprecedented, with reports indicating a significant online and face-to-face hostility directed towards Jewish individuals.

What was already established

Prior to the Manchester attack, the CST had already noted a rising trend in antisemitic incidents, with 2023 witnessing the highest recorded numbers.

Businesses and jobs

Businesses within Jewish communities may face increased security concerns, leading to higher operational costs. This may deter investment and affect local economies, particularly in areas with significant Jewish populations.

Policy and regulation

The UK government is responding to the rise in antisemitism with increased funding for security measures at synagogues and Jewish community centres. There are calls for stronger police powers to manage hate crimes and protests that may incite violence.
