Deregulation, privatisation, and an end to mistrust between government and business will top the new Polish administration’s economic agenda, says Donald Tusk, the prime minister.

“We have to recognise that an economy freed of unnecessary regulations is more effective ... You have to take a machete and cut, cut, cut. Determination is needed, because there is a regulation fetish,” Mr Tusk told the Financial Times in his first foreign media interview since his surprise election victory last month.“The word deregulation is not an empty motto.”
