Aaron Porter was not subjected to anti-Semitic abuse ("Oh, Mr Porter: NUS presidency in Left's sights", 3 February). He was referred to as "a Tory too" in chants by protesters (see a video at http://alexandrews.info/aaron-porter-anti-semitism-manchester/), not "a Tory Jew" as he and some in the media think.
It is hardly surprising that Porter should make this mistake, of course, because he spends most of his time boycotting the marches where similar chants can be heard.
