 However, in a poll November 2019 the public opinion has changed with 78 % in favor of nuclear power and only 11 % against.Prior public support for nuclear power stood in contrast to the stances of the major political parties in Sweden, but after the polls in late 2019 the debate changed and the parties that wants to build new nuclear power in Sweden (SD, M, KD, L ) put forth a demand to the leading government party, the Social Democrats to chose a path forward, otherwise they might break with the standing energy agreement and work to reform the policy towards nuclear power, outside of the influence of the minority government.Sweden has a well-developed nuclear waste management policy.
