Since her departure from the LibDems in the House of Lords, the witterings of Baroness Tonge have been easy to ignore.
This is a woman who says Israel will not last, that she could consider becoming a suicide bomber, that the "pro-Israeli lobby has got its grips on the western world, its financial grips" and that there should be an inquiry into the supposed IDF harvesting of body parts in Haiti. Now she says that she is considering joining Jeremy Corbyn's Labour Party - a move the party's deputy leader, Tom Watson, says he would "welcome".
Under Mr Corbyn, Labour already has a bad enough problem convincing the Jewish community that it takes antisemitism seriously.
Should it allow Baroness Tonge - a woman who regularly indulges in classic antisemitic themes - to join, many will surely conclude that the party's problem is in fact an act of deliberate policy.
