The Swedish parliamentary elections, 2018 has resulted in a deadlock:
- The centre-left Red-Green block, outgoing minority government, has 144 seats (was: 159).
- The centre-right Alliance block, outgoing opposition, has 143 seats (was: 141).
- The populist far right Sweden Democrats party has 62 seats (was: 49).
The Alliance and Red-Green both claim to refuse any formal or informal cooperation with the Sweden Democrats.
The Alliance parties are claiming that the Red-Green government has lost its mandate, that the prime minister must resign, and that they want to form the next government.
With less votes than the outgoing minority government and a refusal to cooperate with the Sweden Democrats, based on what situation does The Alliance claim that they can seek a mandate to form a government?
