Ljubljana - Robert Golob's self-test showed a positive result on Monday so the leader of the new party Freedom Movement, considered to be PM Janez Janša's main election rival, has gone into self-isolation only days before the 24 April general election.

Golob, 55, will participate in election campaign events via videolink until further notice, if possible, or other prominent members of his party will step in for him, Freedom Movement said.

The party is seen as the main rival of the ruling Democrats (SDS) in the upcoming election.
