High-profile Twitter users are boycotting the platform for 48-hours after it was accused of being too slow to act over tweets by grime artist Wiley that have been denounced by the Home Secretary as anti-Semitic.

The musician published a string of posts targeting the Jewish community on Friday, which were still visible up to 12 hours later. One of them read: “Jewish people you think you are too important I am sick of you.”

Wiley has nearly half-a-million followers on Twitter alone. His comments prompted the hashtag #NoSafeSpaceForJewHate on as other Twitter users condemned them and the platform’s failure to act early.
