The Conservative Party candidate for Crofton Park has been suspended pending an investigation, after she compared Islam to Nazism.
Karen Sunderland called Islam "the new Nazism" in a tweet from December, and in November asked why those who follow Islam live in the West.
Another tweet from October last year seemed to ridicule the use of a hijab.
Her Twitter page has since been made private.
Her December tweet read: "Love your optimism. The thing is, religion undermines the hard fought for values and tolerances of progressed countries...suppresses free speech and is auto immune from criticism. This is toxic and where the hostility comes from. Religion is totalitarian. Islam has become the new Nazism."
