An early exit poll for a Dutch referendum on a European Union pact with Ukraine says it is unclear whether enough voters turned out to cast ballots, leaving the vote's validity up in the air.
Reuters and the Associated Press cited a poll showing voters who cast ballots rejecting the proposed agreement 64 percent to 32 percent.
But the poll showed turnout hovering just around the 30 percent minimum required for it to be legally valid.
Dutch Prime Minister Mark Rutte said his government may have to reconsider ratifying the EU pact with Ukraine.
Rutte said his government would not ignore a valid "no" vote in the referendum, but it would take time to decide exactly how it will respond.
The referendum concerned a proposed agreement between the bloc and Ukraine, something that would give Ukraine's battered economy a potential boost.
All 27 EU members have ratified the pact, except for the Netherlands.
The results of the April 6 referendum were nonbinding, but were still being closely watched across the continent for initial hints of what British voters might do in June when they vote on whether to leave the European Union altogether.
