Essex Police refused to investigate an academic who claimed Sir Keir Starmer worked for “genocidal Jewish supremacists”, The Telegraph can reveal.

The force is currently investigating columnist Allison Pearson over a year-old deleted tweet.

While The Telegraph writer has not been told which specific tweet is at the centre of the allegations, she wrote posts about Hamas attacks on Israel and antisemitic signs around this time last year.

Suzanne, a teacher who did not want her second name to be published, told The Telegraph how she reported a tweet posted by Prof David Miller, a former Bristol University academic, to Essex Police in October.

The tweet, which made reference to the Prime Minister confirming that the UK stood with Israel following Iran’s missile attack on the nation, read: “Do you understand now? Do you see what the last decade has been about? Your Prime Minister does not work for you. He works for a handful of genocidal Jewish supremacists.”

Prof Miller, who has 79,000 followers, added: “He’s their errand boy and he will send your sons to die for ‘Israel’.”
