A Facebook campaign calling for Daniel Zeichner to retract a statement linking the party of the Polish President to Fascism has been created by a Cambridge student.

Daniel Zeichner, Cambridge’s Labour parliamentary candidate, made the comparison during a debate at the Cambridge Union in early March. He described the Polish Law and Justice Party, which, although not the governing party in Poland, counted recently deceased President Lech Kaczynski as a member, as "Fascists", and accompanied the remark with a Hitler moustache and Nazi salute imitation.

When prompted further, Zeichner went on to equate David Cameron’s Conservative Party with the Nazis.

The comparison occurred in the Union election debate: "This House believes the Conservatives are ready to run the country again". Mr Zeichner criticized David Cameron for taking Conservative MEPs out of the federalist European People’s Party (EPP group), which brings together centre pro-European political forces from the member states of the EU, and instead joining the European Conservatives and Reformists (ECR), which is a Eurosceptic group in the European Parliament.

Zeichner attacked Cameron for pulling out of an alliance with Angela Merkel and instead, "finding some people in the Polish Law and Order Freedom Party – some people who think that the best thing to do on a Sunday morning is to go out and celebrate the achievements of the Waffen SS in the last war". He went on to propound: "it is shameful that a leader of a major British party in this country has got anything to do with these Fascists across Europe."

Gavin Rice’s Facebook campaign, "Zeichner must apologise NOW" rebukes Zeichner not only for his "tasteless and scandalous" comments, but also for the confusion which led to him incorrectly referring to the Polish party as the "Law and Order Freedom Party", which is an amalgam of the Latvian "For Fatherland and Freedom Party" and the actual Polish Law and Justice Party.

Writing on the website, Rice calls for the Labour Party to "dissociate themselves from his remarks" and for Zeichner to "give an immediate public apology". Zeichner was unavailable for comment.
