In 2014, Stefan Löfven (Social Democrats) won the General Election and became the new Swedish Prime Minister. The Sweden Democrats held the balance of power and voted the government's budget down in the Riksdag, but due to agreements between the government and the Alliance, the government was able to hang onto power. Sweden was heavily affected by the 2015 European migrant crisis, eventually forcing the government to tighten regulations of entry to the country, as Sweden received thousands of asylum seekers and migrants predominantly from Africa and the Middle East per week in autumn, overwhelming existing structures. Some of the asylum restrictions were relaxed again later.
