Folk isn't alone in being targeted by the BNP. Seems anything seen to be classically British or English, is fair-play to be borrowed as BNP propaganda. Fortunately not everyone is willing to allow their traditions to serve the BNP's political agenda.

Royal British Legion (a non political organisation) have publicly demanded that Nick Griffin cease co-opting their poppy emblem in memoriam of war dead, as BNP political propaganda.
Nick Griffin hasn't been simply wearing the poppy on rememberance day like everyone else, but throughout his entire political campaign in Europe.

Open Letter to the Guardian

This is another example of their political advertising on the back of remembrance of war dead. A prior example was to be found during a remembrance day service where a wreath of poppies emblazened with the BNP slogo and a message which read: "You fought bravely to keep this country for your own. Rest in Peace. Now it's our turn." greatly distressed people who had gathered for the service.
