I am pretty skeptical of any pan-European hard left party. They never manage to unite on a national level (too many "-ists" to accomodate), so on a European scale it promises some fun infighting.
Not to mention the irony of the parties that killed the European Constitution and the institutions that could have given them a bigger say in Europe now trying to build that influence in a non existent institutional framework and a rising tide of national selfishness in Europe, triggered precisely by their "non". In the long run, we're all dead. John Maynard Keynes
One member of the executive speculated that at the next European elections, parties would field candidates under the logo of the ELP as well as their own, and possibly exchange candidates across borders.
