The Beeb is often accused of leftist ("liberal") bias, and here one can see some grounds for that, because the story has more inaccuracies than you would expect.
You could start with the name that this report gives to the populist party Perussuomalaiset. They're called True Finns, although the party itself does not use that English name, and the Finnish name does not really translate like that. A better translation would be Basic Finns, or as I mentioned before, Elementary Finns. Or Little People's Party.
Beeb also says but the True Finns' nationalism has no room for Swedish. It excludes Swedish as something unfamiliar to Finnish culture. Polls suggest that most Finns share that view and want to stop the teaching of Swedish in Finnish schools.
That's not quite true, either. What Finns mostly want is to stop mandatory teaching of Swedish in Finnish schools. This is not a change to the constitutional position of Swedish in Finland; it would merely revert - from language politics point of view - to the situation prior to the school reform of 1970's when Swedish was made mandatory to everyone. Those days Swedish was doing a lot better than now when it's slowly fading to obscurity.
I have not seen that Perussuomalaiset would have said they'd want to stop teaching of Swedish in schools. That would be absurd.
Then the BBC writes Instead, young women should study less and spend more time giving birth to pure Finnish children. That is like a faint echo of Nazi ideology.
This is pure rubbish. I wonder who the Beeb has been listening to? Obviously, they don't have a correspondent in the country who'd have any idea of the local politics, so they're relying on someone who they think is ideologically reliable. And the Beeb is either naive or then it insist on following its suspected bias.
Anyway, the election result appears to shake the Finnish politics really deeply. It will be very interesting to see what kind of a government coalition will be formed, but none of the old bases will be workable, because they won't have a majority. And with Perussuomalaiset raising from next to nothing to perhaps the second-highest number of MPs, they have a good case to insist their point of view is taken into account. Listen to the voice of the people.
One possibility is that the largest party and nominal winner, center-right-eurominded Kokoomus, will not be able head a coalition, and the new cabinet will be formed by eurosceptics: left-populist Perussuomalaiset, center-left-populist SDP and center-right-agrarian Keskusta. That would give a big - and well deserved - headache to Brussels, because it would mean that Finland stops being the nice model pupil of the new brave Europe, implementing every directive obediently and to the point and paying up every cent whenever someone asks.
In four years, Perussuomalaiset will have lost much of the momentum they now have, and I expect their bubble will burst, but the next couple of years will be interesting.
