The Swedish capital’s export to Britain fell sharply to its lowest point since the 2007 financial crisis last year, Andreas Hatzigeorgiou said.

Trade between UK and Sweden could take a hit if Britain’s given a bad Brexit deal
“If the negotiations between Britain and the EU go badly… there is a risk that trade between Sweden and the UK could end up on an even lower level than before.”
The economy boss also said the recent fall in export to the UK could be the result of businesses being spooked by Brexit.
He said: “Partly, we have a direct Brexit effect created by concerned businesses. Then we have the indirect effect of a strong pound weakening, which again depends on Brexit. The fall in oil prices… could also play a role.”

Saying the situation could not be tolerated any longer, he added: “The overwhelming majority of the Swedish people would like to have a good relationship, a good trade deal with Britain but it looks like the EU leadership might force us to not have that.
“That’s just undemocratic and it’s a situation that cannot be tolerated anymore.”
The right-wing politician, who’s party has surged in popularity in recent months, said the Sweden Democrats want to secure a good trade deal with Britain once it leaves the bloc.
He said: “I want us to cooperate in as many areas as possible. It’s hard for me to sit here now and [outline] a deal but we want to have trade deals with Britain, we need the British people and the British people need us.
