EU Parliament election results showed an emptying of the political "center" in favor of more polarized options. Conservative leaning voters went nationalist while left leaning voters moved from traditional Pantsuit parties to Green doomsday cult parties. In Britain, the 4 month old Brexit Party thrashed the competition in an election Britain should have already Brexited itself out of.
The EU parliament's primary function is issuing non-binding statements and rubberstamping socialisms that emerge from the EU's bureaucracies. In that light, the likelihood of this parliament doing anything other than showing how irreconcilably divided Europe is appears to be low.
