Rachel Riley from Countdown has embarked on an obsessive targeted harassment and smear campaign against Jeremy Corbyn and other members of the Labour Party UK, She has been promoting a petition which is alleging that Jeremy Corbyn is anti-semitic and should be removed as leader of the Labour Party. Anybody who tries to refute this claim or defend Jeremy Corbyn is immediately targeted for harassment by Rachel Riley and her followers. This also applies to anybody that criticises Israel in any way,  Rachel Riley immediately accuses them of being anti-semitic and her followers target them with abuse and harassment. Rachel Riley is also working with Stop Funding Fake News to bring any news website that criticises Israel into disrepute. Together they hound companies to withdraw advertising from said websites and begin a smear campaign against the website. Rachel Riley is using her notoriety to further her own personal agenda and is behaving in a totally unprofessional and malicious manner. Despite repeated requests from targeted victims neither Rachel Riley or her followers have ceased this reprehensible behaviour. Myself and others have stopped watching Countdown due to the fact that she appears on the program and will encourage others to also boycott Countdown until Rachel Riley is dismissed.
