Diana Štrofová was born on 1 September 1973 in Bratislava as Diana Dubovská.[1] As a 17 years old, she competed in Miss Slovakia contest. After graduating from high school, she worked as an air stewardess.[2] From 1996 she worked at the company Sipox Holding, owned by the oligarch Jozef Majský, whom she married in 1999 bur retained her maiden name.[3]
In 1998 Slovak presidential election, Dubovská won a seat on the list of the Party of Civic Understanding (SOP), financed by Majský. In 2001, she quit SOP.[4] Right before the 2002 Slovak parliamentary election she joined the Movement for a Democratic Slovakia (HZDS), also funded by Majský. When some HZDS members protested that Dubovská, who just joined the party was given a more prominent position on the electoral list than some long-term members, the party leader Vladimír Mečiar argued Dubovská worked to the benefit of HZDS by undermining her former party from within.[5]
Soon after the 2002 election, where Dubovská retained her seat, her husband Majský was accused of a large scale fraud and corruption. In October 2002, he was arrested at the border with Austria, apparently attempting to flee the country in a car with Dubovská using her diplomatic passport.[6] According to some reports, Dubovská attempted to smuggle Majský hidden in her car trunk.[7]
In 2003 Dubovská divorced the jailed Majský and started a relationship with the Czech businessman Jan Štrof. Dubovská married Štrof in 2004, taking his surname. In 2005 they had a daughter.[3][8]
After 2006 Slovak parliamentary election, when HZDS joined the governing coalition, Štrofová became a government member as a state secretary at the Ministry of Foreign Affairs. In this capacity, she served until 2010.[9] Meanwhile, she divorced Štrof but retained the surname Štrofová.[10]
Following the 2010 Slovak parliamentary election, HZDS failed to pass the representation threshold, resulting in the end of Štrofová's political career.[11] Subsequently, she returned to the private sector, becoming a communication manager in the renewable energy sector.[12] In 2025, she became romantically involved with the philosopher Eduard Chmelár.[13]
