Britain’s decision to quit the EU was all it took to terrify Finnish voters, with more than two-thirds now affirming their loyalty to the bloc.

Finnish voters dealt a blow to Europe’s plans to rescue Portugal and other debt-ridden economies, ousting the pro-bailout government and giving a major boost to a Eurosceptic nationalist party.

A nationalist party that rejects bail-outs for Portugal and other debt-ridden eurozone members is expected to make strong gains in Finland's election today but remains unlikely to join the next government, according to a series of recent polls.
