Please correct me if I'm wrong - I'm not as up on my political theory as I should be - but:
The Scandinavians are Social Democrats. What Labour has been for most of its history and they practise a mixed free market economy with the government doing some things. But not "the workers owning the means of production" - even though that was in Clause IV of the Labour constitution.
Whereas Democratic Socialism is the workers owning the means of production, through cooperatives or the government with lots of Trade Union power (Tony Benn would called it trade union democracy or soemthing I think) - and so involves lots of nationalisation and workers' representatives getting seats on the board - and lots of government intervention into the market.
Social Democracy in Scandinavia means quite to very economically liberal with high welfare payments and high taxes. That might have been what New Labour would have gone for, if they thought they could have got the tax rises past the electorate - but maybe move towards it slowly.
Corbyn though is a Bennite, as he was friends with Tony Benn and was on his leadership campaign team - and I understand is more of a democratic socialist.
This is not just People's Front of Judea vs. Judean People's Front - this is just what happens when you allow political philosophers to define their terms too similarly.
