Pacevičius confirmed it to BNS himself on Wednesday.
"In essence the decision has been made. (…) The Presidential Office has been informed about my wish and her Excellency will make the final decision. Stepping down after the end of the term is common, and, of course, I will look for opportunities to stay in the civil service but in a different office," Pacevičius said.
"A statutory office needs to serve a certain number of years – 20 years – to get a pension. I have served 22 years already and, I think, it's enough for me in this position. I have worked in this area for 15 years, so perhaps I should change the sphere," the SIS head said.
The Presidential Office also confirmed it to BNS on Wednesday that a new head of the SIS will be looked for.
"After the SIS head's term ends, a decree on the dismissal of Pacevičius will be brought before the Seimas. Then a decision on an acting SIS head will be made and the procedure of looking for a new head of the service will be launched," Daiva Ulbinaitė, an adviser to the president, told BNS.
Asked whether he had suggested any candidates to President Dalia Grybauskaitė who appoints the SIS' head, Pacevičius said he had not.
"So far nobody has asked me anything. Her Excellency will make decisions, and if my opinion is needed, I will give it, if she asks," Pacevičius said.
Sources say the incumbent 1st deputy head of the SIS, Saulius Urbanavičius, is one of potential candidates. Grybauskaitė appointed him in January.
Pacevičius assumed his office in October 2007. His term ends in the middle of October soon after the Seimas election on 14 October, meaning that a new SIS head will be approved by a new parliament.
