Eurosceptic trend in Denmark and Greece

In troubled Greece the opinion polls reflect voter discontent, with the radical left-wing Syriza bloc now neck-and-neck with the ruling conservative New Democracy.

Both are on just over 26% each, so Syriza is likely to enter the European Parliament for the first time - and in strength.

In affluent Denmark the People's Party (DF), with a nationalist and Eurosceptic outlook, is topping the latest polls. Centrist parties are second and third.
