Jansons was elected with 49 votes over 45.
Thursday morning he told Latvian Television that his priorities in the office, should he be elected, would be working in the health sector, defending people's rights to just remuneration, and protecting the rights of people with physical and mental disabilities.
The second candidate, Ilze Bērziņa-Ruķere, a lecturer at Riga Stradiņš University, was rejected as 43 MPs voted for, and 51 against her candidacy.
Jansons was elected in the second round of voting. According to Latvian Radio, Jansons wasn't elected in the first time due to a mistake by a Regional Alliance MP.
Jansons, born in 1973, has been Latvia's ombudsman since March 17, 2011 when he, a little-known lawyer, was conjured up by the parliament.
Experts are equivocal about Jansons' performance in office, saying he has paid more attention to resonant cases like children's rights, however staying away from other topics like minorities. However they claim Jansons' activities have made the office of the Ombudsman much more recognizable.
Previously Jansons, a lawyer and economist by education, worked as the head of a health insurance company.
