Finland's prime minister had good reason to go out and celebrate, because her country is joining NATO, her Polish counterpart said on Friday, backing Sanna Marin's right to party as she faces a storm of criticism at home over leaked videos of a night out.
Marin said on Friday she had taken a drugs test following the publication of video footage this week that showed her partying with friends. She vowed she had never used illegal drugs and said her ability to perform her official duties had remained unimpaired on the Saturday night in question.
